I have an older dual tank style air compresser for sale. not sure on the brand or anything like that, i know it works and everything. FINALY stepped up to a nice big one (5HP, 80gallon) so this is no longer needed. I also have a REALLY small Craftsman one too, $30 for it or $70 for the pair.

Craftsman is a 3 gallon 1.5HP

The other i would guess to be around 8-10 gallons and probably 2HP or bigger.

gimme a call some time between 4pm-9pm if you'd like 319-241-4059, Keith
