    I have an Iwata Eclipse already and am now thinking about buying an Iwata micron but I can’t decide on which one to buy, it is between the CM-C plus and the CM-B. I know it is popular but I defiantly will not be buying the CM-SB as I do not like the side cup.

    I like the look of the CM-B and it has the 0.18 needle but the cup is small but I am favouring this one.

    The CM-C plus has the advantage of the Mac valve but has quite a large cup (same size as my eclipse) and has the larger 0.23 needle so less detail.

    I just want some opinions before I go ahead and purchase.

    You can get the cm-c+ and order the .18 set up to put in it . The cup on the B has a funky cup and no lid. When I was trying to pick which one I wanted to buy I got advice from some of the artist that happen to be over at Coast Airbrush on the day I was talking with David Monnig on the subject and listened to the pros and cons between the B, C, and C+ , Almost all said the C+ was the easiest to clean out the cup between color changes. So when I ordered mine I also ordered the .18 set up.
    As far as .24 vs .18 on detail that is all in the hands that hold it. same as going to the .15 from the .20 on the H&S Infinity you can pull the same line but you will have to learn to reduce you paint more and lower your pressures way down which in some cases causes more issues when painting when you are fist starting out.
    Another word of advice on the Micron Leave the crown cap on until you get use to it the parts are not cheap to replace.

    Thanks for the reply and info, I did notice that the CM-C plus can be upgraded to the 0.18 setup but with that upgrade price on top of the airbrush it comes to a fair price in total. I would then be left with 0.23 parts that I would probably never use.

    It’s a hard decision!

    I started using the .23 straight out hte box. I only switched to the .18 when the fluid nozzle caps threads broke off inside the head unit. I blame being heavy handed on it breaking but I did send it in to IWATA and they replaced it for basically free I did pay shipping to send it to them and I had figured they would say users error but they sent me a new one. I have yet to put it back in but I really do not notice a huge difference between the two on fine line work.

    Perhaps i should consider the CM-SB after all, although I'm not sure how i would like the cup on the side. It does seem to be a popular choice.

    Going from gravity feed to side feed takes a bit of getting use to mainly due to the cup being on the side and the weight will feel off until you spend some time with it. Yes I do own a side feed and over the time I have had it , I have tried getting use to it. For me it just always feels unbalanced in my hand vs the gravity feed but that is part of getting use to it.
    You could also consider going with the H&S Infinity 2 in 1 that way you have not only a small cup but a larger cup that you can switch out. it is .15

    That was my worry about the side feed, aside from it looking a bit odd the balance thing it’s the cup to one side was a thought too. I also often like to use just a couple of drops of paint in the cup, with the side feed it looks like the cup has to be half full for it to work?

    I only use the CM SB and love it mainly because I can use it in any angle I want even upside down if I have to

    No you can put just a couple of drops in but remember you are going through a super tiny nozzle which means you will be adding more reducer so 2 drops paint 6 to 12 drops reducer adds up.
    As far as the balance thing it is just takes getting use to. Some love the feel and some like me just do not care for it.
    Up side to side feed is you get full view of the needle .

    Here is an affordable suggestion on sidefeed and not being sure if you will like it . Buy a Master https://www.amazon.com/PointZero-Dual-Action-22cc-Side-Feed-Airbrush/dp/B00G5D3PJE/ref=sr_1_1_sspa?ie=UTF8&qid=1517412752&sr=8-1-spons&keywords=side feed airbrush&psc=1
    21 bucks is a small price to pay to see if you will even like it .
    I made the mistake of buying one of the higher end side feeds when I first started and hated it but it did find a new home. Now years later I decided to give a side feed another go so that is the one I bought and until I feel I like it I will not spend the big money on the micron version .. LOL
    Just a thought .

    or if you want one more like the micron https://www.amazon.com/Detail-Preci...517412999&sr=8-19&keywords=side feed airbrush

    I am not a big fan of a "C" cup on a brush that I describe as detail oriented. For that reason I tend to gravitate towards the "B" or "SB" versions, with the gravity fed "B" being the most prolific brush in my collection. I actually use an Iwata HP-B+ that is highly tuned over any of my Microns, but your mileage may vary ;).

    If you are thinking about going Micron C or C+, and converting to a .18, you really should also look at a Procon GSI PS770 from Sparygunner. Aside from the finish, they are for all purposes identical to the Iwata version. Save you a BUNCH of money.

    I recently got a CM-C + and it goes without saying that it’s unbelievably good. It has the .23 setup and it’s only personal opinion obviously, but I can’t see that a .18 would be a great deal finer. Common sense tells me it must be, but I really don’t think my eyes would ever detect it. Just some food for thought.

    I dont think that there is much difference between the 0.23 and the 0.18 set up and it depends on the paint you use how much you need to thin it down the 0.23 will allow a bit thicker paint but I never thin my paint and I use a 0.18 setup
    as for the cups I am with Dave the large c cup blocks the view over the airbrush to much I did own a grex with the B cup and liked the way I could see over the cup but I didnt like the way it sprayed so that brush went to a other home and I do own a 0.5 Iwata revolution but I only use it for large coverage or to spray micro pearls or metallic's but again I dont like the big cup and I tend to forget I need to hold it at a forward angle
    I think the best way to find out witch micron suits you best is to go to your Iwata dealer and ask if you can at least hold them before you buy one .

    I was under same issue when I bought my CM-C, was between B and C, don’t like the mac, finaly got the C and love it, but if I have to but it again, definitively I would go with the B, the C cup is way to big for the amount of paint that you will use in that kind of brushes. And between my CM-SB and CM-C (.18 and .23 respectively), the only diference that I found with my limited experience, is the weight and balance, beside the dilution of the paint, I prefeer the CM-C.
    Hope that helps!!

    I personally dont see the value in getting the plus model with the inbuilt Mac Valve, I have one on my airhose so it doesnt matter what brush i use i have that control. I'd rather spend the extra money on supplies

    As @MarcosD has stated, the C cup would rarely be filled for what you would use a micron for and if you are doing a large area then you just top up the smaller cup as needed.

    I have the CM-B & CM-SB and at my skill level i cant tell the difference between the .23 and .18 and for me it wasnt about 'pulling finer lines' it was more about the better atomisation at low pressure. I can honestly say that they were the best investment i've made and I hear a lot of people say that the weight of the side cup is an issue, but i can say i didnt notice a difference, its not as if its the equivilant weight of another airbrush on the side.
    As for your concern about needing to half fill the side cup that is not the case as has already been said, you can literally put just a drop or two in there as it feed into the bottom of the cup and is drawn up the side of the cup to the brush. You can also get different size side cups to use so if you are frequently topping up the cup then maybe a larger cup may be useful for those odd occasions.

    One thing you may not have thought of is that the Side feed allows you to change colours with relative ease as long as your paint in the cup is below the level of the tube that sits into the airbrush.
    just get a side feed bottle and fill it with your chosen cleaner, remove your current paint cup, insert the cleaning bottle, spray out into a pot and then replace with a second cup with your next colour.
    the cup that comes with the brush doesnt have a lid, but the next size up does so i've bought several of those for the times that i'm wanting to use multiple colours without having to 'waste' what is in there.

    Ultimately the choice will be yours and like you I was trying to figure out what would be best and eveyone seemed to really like the side feed and when i first got it i couldnt see why everyone was so keen on them but once you get use to it they are great. my only 'issue' was with the cleaning as i was so use to cleaning the gravity feeds and this seemed so foriegn.

    A lot of members here will quote an Eclipse CS and a Micron of some description and its true, with those two brushes you would have 95% of your needs covered.

    Sorry this turned into a really long post, but i got a little carried away lol

    I thought the CM-B and the CM-SB were both 0.18mm? I think you are right about the CM-C plus, the cup is large, that with the MAC valve is just extra bulk. I am leaning towards the CM-B I think.
