i just bought one at home depot about a month ago for the new loft. It was on sale at the time, but check it out anyways.
it's a rigid 6.5 hp/ 16 gallon, normally $109, it was on sale for $59!!!
I have been using it more then i would like to recently and i am pleased with its performance. it comes with a bunch of attachments and replacement filters already...not to mention that it... blows too!
nice for blowing crap out the loading dock.
I couldnt find a link, sorry, but it might be something to look into.
