Buy a better piston compressor with oil-filled sump, because it will meet all the above requirements.
Choose quality gun. It needs to be economical in air consumption and do not take it more than it can produce air compressor. Do not worry the cost of a good paint, because they are about as quality painting two or three parts in the service station.
