This is one of the best bargins out and is significantly lower priced allowing for a pretty nice receiver.

My suggestion would cost you a bit more than your budget mentioned.

Yamaha RX-V2500 receiver $600
Axiom bookshelf M22tis $440/pair
Axiom surrounds QS8s $500/pair
Axiom center VP150 $385
SVS PB10-ISD sub $429

(If you want an awesome total system for a fair amount more money replace SVS with Axiom EP500 subwoffer $1,150)

Been doing a ton of research on the subject and that is what I come up with for your size room and budget.
