I have the chance to get a Onkyo TX-SR800 ( http://www.us.onkyo.com/model.cfm?m=...class=Receiver ) receiver that is 2 years old for $300.00 shipped. I am a little worried about buying it because if it goes out I am pretty sure Onkyo will not fix it. The other receiver I am looking at is a Yamaha HTR-5740 (http://www.yamaha.com/yec/products/HTIB/HTR5740.htm# ) for $199.99 new. I will be using this receiver for movies AND music in a semi large den area with 18ft cellings. They will be used to power 2 polk rt600 towers (http://www.polkaudio.com/home/produc...ker=2&recent=1 ), a Polk cs400i center ( http://www.polkaudio.com/home/produc...er=41&recent=1 ) and a pair of rt28i for the surrounds. ( http://www.polkaudio.com/home/produc...r=178&recent=1 ) Which one should I get?
