My buddy sold me his 13lber....Campbell & Hausfield unit. I need an impact gun, hose, attachments, etc, etc. I know 13lbs is not a lot, but this compressor is a work horse. We took the rear subframe out of my 335 with it, no problems. Will work fine for the small stuff I need to do on the car.
if you're looking for a good one check Sears for their "floor models". My buddy got a 20lber that was a floor unit marked way down.
