I got this one for work and works out well in the garage too. Small enough to fit under a workbench and you can still roll it around if need be. Plus it has a higher than average (for a compressor this size) CFM output; 6.0SCFM at 90lbs. That's more than enough to run an impact wrench. It also has two outputs and the output/gauge panel can be mounted in between two 2x4's at eye level if you like. I'm sure you could find it cheaper if you looked around too. If I remember right I bought mine for about a hundred dollars cheaper than this.

FWIW, I use my Powertank as my garage compressor.
It's portable (obviously) and is great for filling tires (of course), but will also operate an impact wrench and air blower. Wouldn't want to use it for any long duration projects (like painting) but it works fine for any thing else.
$15 for 10#'s where I go, but I've seen charts that vary between $10-20.There's an idea... I hadn't though about a powertank. What does it normally cost to refill? Ron

I just refilled it and it lasted me a year, but I don't air down very often only 3 times last year and mainly use it to top off the tires on my various cars and as an air blower to clean parts, etc.
Agreed.CO2 in the garage does seem like an interesting idea, although you should probably get the 20# tank b/c the 10# seems to go pretty fast when using air tools.
