People say Denon makes the best sound at this price range. I got Denon 1913 for 69 dollars at BestBuy's clearance. If you check my thread below, you might be able to find one. Denon 1913 is last year's model with a 450$ retail value.
I also have a Yamaha 673 in my home right now but I plan to return it because i got the Denon at such a good deal. The Yamaha has more features but people say it doesn't sound as great as Denon. I plan on getting next year's clearance at a cheap price too. Easy way to upgrade without breaking the bank or you could just buy new but I don't see any point. Best Buy also sold me insurance on the receiver at 20$ so they will replace my model if it ever breaks but since they don't make that model anymore, they will give me the new version. Buy clearance, it's a good deal.
