Where to rent an air compressor in Portland?

Anyone know of a cheap place in Portland to rent an air compressor and impact gun for a day or two? Everywhere I've called has been pretty expensive... I suppose it'd make a lot more sense to just buy one but I can't really afford it right now.

I just want to replace my a-arm bushings... from what I've heard the bolts are often pretty impossible to break loose without air tools...?

If anyone is selling one cheap let me know... same goes for a decent floor jack.

Doh, meant to post this in talk... wouldn't let me delete it. If a mod feels like doing so I'll repost it in talk.
