I also picked up one of those portable tanks at HF(or Northern, etc.) that I hook up to the compressor with one of those clipon inflators and let it run until compressor shuts off (ie tank is full). I can get about 15 psi in each tire which allows me to pull it up on a trailer. You could supplement with one of those little compressors Brad mentions....they have pretty slow fill rates but the portable tank will speed things up a bit.
