if you have the money to spend, about 350 bucks, i would reccomend the Iwata LPH-400. its a gravity feed that comes with a 1 litre aluminum cup, and it sprays great glass like coats. i use it only for bc/cc and the custom stuff. i have a cheap gun for all my primers and sealers and such. get the 1.4mm tip with the iwata, its great for bc/cc. the gun also looks really nice. it has a gunmetal type finish to it. its also very light weight and easy to maneuver. good luck with whichever gun you decide on.
