Paint gun recommendation

Guns really are like engine oil. It comes down to preference. I, personally, still use a 12 year old Accuspray 10 gun with a #5 cap for clear, and #7 cap for heavy metallic bases. All my primer guns (all cheapies) are set individually to run sealers, heavy urethane fillers, etc. My Pop has a Devilbis Millenium GTi (I gots to get me one of these!) But I've known guys who swear by Sharpes (I swear at 'em), Binks (love 'em), etc. It's like any other tool. It's not so much the gun, it's the guy who's pulling the trigger. Though if you're new to the ballgame and getting used to it all, Sharpes is usually the most forgiving gun out there.
