I have a Master airbrush gun and compressor. It's a dual action gravity feed. The compressor has a water trap, an automatic shutoff, a holder for 2 guns and I can set the psi to whatever I want (vs high/med/low). I do cakes as well so I bought this one. At first it was a bit frustrating because it's very temperamental and I was inexperienced with airbrushing. But after a few times practicing and figuring out how to thoroughly clean it, I'm very happy with it. They probably all work fine, there's just a learning curve. I make a point to clean it well after each use.
