This is my airbrush. It's simple, easy, and I'm happy with it. Doesn't gum up, cleans easily, sprays beautifully. I do have one problem. I don't seem to be able to get a really fine line like I would like for 1/72 shading. It does better on larger highlights...but panel shading is nearly impossible. All that said, I think my problem is technique, not the airbrushes fault. (In fact, I think WMChengs brush is similar...which would prove I'm just not good with this thing) The finest line I can get is at low PSI (12) minimal flow, and close up...works okay, but it seems like I should be able to do better.
Any advice for me? Would upgrading to a dual action help me out a lot? (and why? )
