Thanks for the advice everyone. That Behringer has gotten good reviews, and it is about the price I want to spend. And yes, I do have a pair of Outlaw Bookshelf speakers collecting dust!

I was looking at the manual for the OAW3, and it only shows a hookup for a subwoofer. Mono of course. Would the setup for rear surrounds be: stereo RCA to 1/8" wire -> transmitter unit -> receiver unit -> 1/8" to stereo RCA wire-> amp -> speakers?
