just my
...
About a year ago I bought one of those testors aztek setups with the air cans. It was my first AB. for a while it was great, I could do things that were impossible without it. After a while, it got to the point where I would just rather not airbrush than use it, it got plugged too easy, was hard to clean, dealing with tose stupid cans, just annoying. recently, I bit the bullet and put some cash down for a badger 155 anthem set and a paasche compressor. sure its a little noisy, but now I cant wait to airbrush!the difference is like night and day. Its easy to clean, great line control, great air control.
I dont know anything about other brands, but coming from an aztek, I think anything would be an improvement IMHO.
ps although I never did try that aztek with a compressor, maybe my experience would have been different that way, but I doubt it.
