I just got an H/K AVR525 from http://www.onecall.com (refurbished) for around $500. Since it retails at $900, it's a damn good deal. It's got the sub crossover, DD ES, DTS EX, pre-outs, 7.1, etc. The remote sucks, but other than that, it's pretty cool. Worth looking into, at least. Hint: it sounds way, way better (even with 2 channel) with Dolby Pro Logic II Music turned on for CDs. Just opens it all up.

I am the Doctor, and THIS... is my SPOON!
