I'm no professional painter, but my dad and I painted my car with a DeVilbiss. We bought a three gun kit out of Eastwood that has a gun for primer, topcoat, and tuch-up work or something. I don't recall the name or model number but i thought it performed well and i'm happy with the results. I don't know if our paintguns are made for professionals but it worked for what little we had and what little we will have. I'm sure paint guns are just like everthing else, you get what you pay for.
