Hi. I am a retired hobbyist with no air brush experience. I do make jewelry for fun and have a steady hand. Would a Master G444 be a good buy because of 3 the different tip sizes ? Prices are much higher here in Canada for the same products so big-name brushes might not be the best idea for a rookie. I am wary of cheap no-name kits because of parts availability. I assume TCP Global must have parts available ? Thanks for your time. Greetings from Northern Québec. Send us some heat.
I have a good many airbrushes, which will include the Master G44/G444 and up to some of the top of the line name brand brushes. I would not recommend the G44 or G444 brush from TCP Global. While TCP Global does say that they have replacement parts, what they do is sell the parts as a kit bundled with other things you will not want, or need. I found the brush to be seriously lacking in quality, and I could not get it to work acceptably for more than just a few minutes, despite a concerted effort on my part.
Now, you may take it that I am just diss'ing the inexpensive import, but I assure you that is NOT the case. I have many other Chinese brushes, some of which I would recommend highly! I have one that looks almost identical to the Master G444 (and is less expensive to boot), even came with the different heads ( the G444 only comes with nozzles and air caps to change sizes -along with needles). The other one I purchased (for $25US) came with full head assemblies as well as needles. Build quality of the good one is night and day different than the Master G444
The PZ360 kit ($25US) is on the left, and the Master G444 ($39US) on the right -
I would not use the Master brush to water my plants, while the PZ is part of my regular inventory of brushes that I use. Trust me, while they look almost the same, the two brushes above have nothing in common, other than a similar thread size on the head assemblies - virtually every other part is different - some by little, some by a lot! Now, I am not real sure I would recommend the PZ360 right out of the box either. The reason being, it is what it is, and if you need replacement parts there would be no guarantee you could get them, or that the brush would work the same once you did. At $25us for the kit, I personally would just buy a new brush and be done with it.
Purchasing any of the brushes in this range (while I have a good quantity of them and feel they work really quite well) you are really taking your chances, and will largely be on your own after purchase should you have problems with it.
I would think, that if you are looking for a name brand brush, that will have at least some sort of backing - the Badger line of brushes may be your best bet to get your feet wet (their support is excellent).
. I could tell you stories I have heard from people cross border shopping. Also consider customer service and support and availability of replacement parts not having to wait weeks for order stuck at the border because customs has decided they need to see what you are buying.
