Not to discourage the purchase of an Outlaw product, but since you are looking used ATI (the maker of Outlaw's multichannel amps) amps are regularly listed on Audiogon and ebay. I got my ATI 2005 used just before Outlaw released the 7500/7700 and it has been a consistent performer for several years.
