A good price for the power. Most of the 3 gallon portables have pretty wimpy pumps. Harbor freight has 1/3 HP, 3 gal, .6CFM @ 90 psi on sale for $60 right now ($10 off reg.), and this is a lot better for only $10 more. Plus it's the craftsman name, and presumably better warranty.
I would be sorely tempted if I hadn't just bought a used 2HP 3 gal pancake through craigslist this AM. :-)
