Lowe's offers the Porter Cable 6-Gallon 150-PSI Oil-Free Pancake Air Compressor, model no. C2002, for $99 with free shipping. (Amazon charges the same, although stock is limited.) That's $23 under the lowest total price we could find for a refurb elsewhere (this unit is new), although we saw a new unit for $10 less in July. It weighs 34 lbs. and features a low-amp 120-volt motor and two air couplers to support two users.
