I found a rebuilt air compressor on Craigslist:
"I have 60 gal. compressor for sale. The compressor has been rebuilt. It has a brand new pump (15.8cfm@90psi), a brand new 5hp dual cap. motor and a new check valve. I was currently rebuilding this but received a new one for xmas. It needs to be finished, putting the supply tube in and guard for the belts. If you are handy with tools this would make a great compressor."
Any help on whether this could be a good deal or not is appreciated.
