johnpo, about two months ago I purchase a campbell-hausfeld "QUIET-AIR" compressor from Wal-mart. It was on clearance, so I got it for about $50 (I think). This was replaced by a new incoming model, pretty much the same features. It comes with an attached 2 gal tank, auto shutoff, fully adjustable pressure regulator, and separate tank guage, coiled self storing hose, various nozzles. This thing is awesome!
I started off with canned air, the the cheap refillable 5 gal tank, then a cheap second hand diaphram pump, all of which totaled more than 3 times the price of what I paid for this compressor I just got. (and oh, yeah...it has enough power to use it for inflating anything, plus you can use a nail gun with it, all about the size of a boom-box)
