I just put a Yamaha HTR-5740 into my bedroom system, runs $ 200 (JR, who didn't have them) to $ 230 (Onecall, who did), and it's got some great sound. it won't bowl you over with features, or YPAO, but it kicks the snot out of the Sony STR-DE915 whose place it took.
I use it with a set of Infinities (which are pretty nuetral, like the Athenas)- Alpha 20 bookshelves in front, Alpha center, and Primus 140's in the back.
I also picked up a Velodyne VX-10 subwoofer, which doesn't have a lot of low range- 36 to 120 Hz at 100 watts (150 peak), but at 128 bucks (only in silver, also from Onecall), it will fill the need til next year's income tax return.
