1. compressor must be with a tank.
1a. chinese compressor. Must be two piston type for longer life.
1b. good brand compressor. I'd choose something with fridge compressor type, like Silent Air or similar.
So, generally two options to choose from. Cheap and expensive, but there's also California Air, that's something in between, I have no idea how good they work.
I first bought two piston type, which worked normal, then built my own based on commercial fridge compressors, that's high end thing.
