I second the denon suggestion. I run an Epic80 on a low end Denon 1602, and it's great. I will only upgrade once I move into a bigger place, as I will need more power (I run the setup without a sub, for now). But for a regular every day user, Denon at that price cannot be beat IMO.

You can actually get some refurbished ones with a 90 day warranty from www.ecost.com, and they are great deals. I have heard very good things about ecost from audio boards.
