CPO via eBay offers its factory-refurbished Porter Cable 6-Gallon 150-PSI Oil-Free Pancake Air Compressor, model no. C2002, for $69.99 with free shipping. That's tied with our mention from April, $29 less than a new unit today, and the lowest total price we've seen for any 6-gallon pancake compressor. It weighs 34 lbs. and features a low-amp 120-volt motor and two air couplers to support two users. A 1-year CPO warranty applies.
