you can pick up DeVilbiss Finishline guns at right around $100,I don't see a reason in your situation buying expensive gun and only use it once or twice,unless you have plenty of cash.If you're shopping for one gun to shoot base and clear,get fluid tip & cap between 1.3 and 1.5, anything bigger and your clearcoat won't atomize like it should and end up with heavy orangepeel,
