I'm an Onkyo/Integra fan. I use Integra AVRs in my Home Theater Room and in a much smaller, video-centric set-up in my family room. I also use an Onkyo Pre-Pro in my more elaborate two-channel system because I'm hooked on room correction.
The Onkyo TX-NR 709 is available at <$550 from big box discounters and it features full-range Audyssey EQ (including the critical subwoofer correction). If you have more to spend, you might look for something from a premium brand, but the 709 is an excellent option for the +/- $200 premium vs. repairing your existing AVR.
