The best one? You could get opinions all day long on that question and end up more confused than informed. Everybody has a preference. And that is usually the one they have now.
Any good brand name gun, that you can get parts for, that will last and will not consume more air than your compressor can provide will do what you want.
Eastwood has some good DeVilbiss two and three gun sets for under $200.00. That is if you want to get a bigger bang for your buck. (I'm sure I'll get some flac for that suggestion.)
Or check Ebay if you trust not holding it in your hand before you buy it, or you could try the local pawn shop. That is, if you don't insist on brand new.
I picked up a top of the line Binks suction gun for $20.00 at a pawn shop. Got a rebuild kit, cleaned years of built up paint off it in a can of carb cleaner, and have a great gun that has lasted me for 30 years. Got another one at a swap meet for less than $50.00, same deal, cleaned it up, rebuild kit and good for years.
So high end ones are out there if you don't mind used, and good ones for new if you look around.
