Looking for audio recievers

[_-Gunslinger-_]

Ok I cant seem to find any audio recievers on the internet for under $150, bestbuy sells them for like $100 but I figure I can get them cheaper.

Im looking to "pimp" out my sound system on my computer with a reciever. I have 4 of these 5.5 inch shelf speekers sitting around and figured if I dumped 200 bucks into a sound card and a sub and a reciever that my sound system would kick ass.

Anyone have a site I can check out that has good sound equipment? I dont want crappy ass computer speakers, they are small, suck, and I already have speakers.
