I've read and heard that this speaker package is one of the top low-end packages out there. I got the entire thing for $350.

Now I need a good, affordable 6.1 channel receiver that will put my "good" speaker system to use. I've done some research and I'd like to keep it under $250.

Please help me!! Thanks!
