Hi anazoth!!!! firstly, what do you intend to do with it? suction feed such as the one above is great for tshirts and for covering larger areas as you can really crank up the pressure and sling a whole jar of paint, although they are not the first choice for detail work, if you are going to focus mainly on canvas/paper art or smaller then i would be looking at a gravity or side feed....i agree with tigertron on the compressor , you really want one with a tank, doesnt have to be massive lets say 15 - 20litre as a average would serve you well..... I have a compressor like the one pictured above and its crap! moisure problems, pulsating air.... yadda yadda yadda .... crap!
as mentioned above, comart is a great paint to start with as it flows easily through smaller nozzles and requires little reduction, spectra tex is also a good paint for beginners and can be used on all surfaces , from paper to wood to metal etc.
where abouts in the world are you, this also effects which brush i would suggest for you.... im a badger man, er er ...... meaning i use badger airbrushes..... not that im some kind of half man half badger thing.....they are a great brush, high detail, affordable, reliable, cheap to find replacement parts .
let us know mate give us a bit more info on what your intentions are, and also a price range of what you can afford total and people will probably post you some better deals!
