If you are not looking for show car type finish, I suggest getting one of the better quality guns offered by HF, Northern Hyd or the like. You can get a Binks, DeVillbiss,Sharp knockoff for prolly no more than 50-60 $ If you want to go high tech, you could start with an HVLP. the benefits would be, less overspray due to better transfer of paint from the gun tip to whatever you are spraying, and it takes less material (paint) to get full color on whatever you are spraying. I do not recall a significant difference in the learning curve (between HVLP and a conventional cup gun) for using the gun. Whatever you do, do not buy a used gun. Reading is helpfull, but nothing can be substituted for experience. Make sure you use a dryer to address moisture from the compressor and drain the tank. The most important tip I can give is this, You cannot clean a gun too thoroughly after use, nothing is more frustrating than starting to spray a color and having chunks of a previously sprayed color come shooting out to mess you up! Additionally, make sure you have enough compressor to keep up with the gun, add a pressure gage at the gun to account for pressure drop from the compressor, use 3/8 hose at a minimum, and last but not least, never ever loan your paint gun to anyone. Loaned guns usually come back trashed, or at best primer guns. That's my 2 bits!
