OK, the room size is roughly 15 x 24. The TV is along one of the 15 foot walls (if that makes any difference).

I was looking online at BestBuy and they have a Pioneer receiver 5x100watts with Dolby 5.1 for $179. ( http://www.bestbuy.com/site/olspage.jsp?id=1077628262859&type=product&productCategoryId=cat03031&skuId=6364846 ) Is there something special I'm looking for besides those basic specs? Is this a decent receiver for what we've been discussing?
