http://www.spearitsound.com/Multi-Channel_Power_Amps-NAD_T955_Refurbished.htmlI have a buddy who bought a 955 from them a couple weeks ago, and he likes it VERY much... I have also bought several components from them as well, good guys.
Ben, If you want any help buying an amp, I would be more than glad to help spend your money.
p.s. accessories4less has this amp.

It doesn't list 4ohm ratings though. But, i'm sure you could make some phone calls and get those.. This amp also has XLR inputs, incase you ever decide to go the XLR rute.
