I did end up buying the Puma brand PD-1006 from Buzzard Gulch, through Ebay. I highly recommend it from my use so far. It takes my tires from 22psi to 50 psi in just under 2 minutes per tire. After doing all four, it only takes the time to put away my airs hose and pressure gauge for the compressor to be cool enought to touch the cooling fins.

It claims to be able to run air tools, but I haven't put it to that test yet.
