Just wanted to tap the collective wisdom of the group on this one. I have a small twin-tank 4 gallon Porter Cable oil-free compressor that is not meeting my auto repair needs. I'll keep it for woodworking and small jobs like filling tires, but need a big honker for impact wrenches, cutoff tools, and light sandblasting on the old (57) Dodge trucks my wife wants me to restore.

I have 240V in the shop, and a budget of around $600. Looks like there are several oil-lubed single-stage compressors of about 60 gallons with 10+scfm at 90psi in that price range. A local store has a Porter Cable with some light cosmetic damage (paint on the tank is scraped down to the primer) marked down from $580 to $400. Comments?
