Integra 9.8, 7.1 channel processor, used, $300. Canuck Audio Mart. A bunch of Anthem processors, used, low prices.

Used multi channel amps are plentiful and relatively inexpensive. Go with a quality brand - Anthem, Parasound, Rotel, Yamaha, Marantz ...

You can get a nice component system for less than a new receiver.

Good luck!
