Factory Authorized Outlet via eBay offers the 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 last month as the lowest total price we've seen. (It's a current low for a refurb by $10 and $59 under the best price we could find for a new unit.) It weighs 34 lbs. and features a low-amp 120-volt motor and two air couplers to support two users. A 1-year Porter-Cable warranty applies. Deal ends August 10.
