Name brand makes all the difference. I have a porter cable twin cylinder compresor that works great and you can add air by adding another hose, it fits in the back seat of a car and will even run my framing nailer, as important is a decent ratchet with good sockets, I have a set of 188 pc craftsman from, well along time ago, and watch pawn shops for matco and snap-on at some great prices but you have to do your home work.
