Rjones -- I just "ordered" the HK AVR 525 from Harman Kardon's ebay account. They sell them refurbished with warranty -- the winning bids typically end somewhere between 450-560. My winning bid was 480, but it was $515 after shipping. You should check it out, as HK seems to put them up for sale daily.

The main reason I purchased it was to replace my cheapo one, which had a high THD rating of .7% at some rated frequency like 2 khz. I'm anxious to hear if I do perceive a difference -- seeing as the HK will be a bit beefier in power.
