Home Depot offers the Porter-Cable 6-Gallon 150-PSI Oil-Free Pancake Air Compressor, model no. C2002, for $99. (Amazon has limited stock for the same price with free shipping.) Opt for in-store pickup to avoid the $12.49 shipping charge. That's tied with our mention from last November and the lowest price we could find by $21. It weighs 34 lbs. and features a low-amp 120-volt motor and two air couplers to support two users.
