Part of the reason I went with a refurb (besides the cost) was that it has been re-evaluated in the factory and works correctly. I would rather know that it works well, even if it didn't at one time.
In any event I will get mine this Friday so I can give you guys the rundown on Harman refurbs.

I will say that buying from HK's eBay store was painless and the transaction went through on a normal Visa card.
Seth=L : When you say that HKs are nothing amazing, are you referring to the MSRP vs performance, or the street price vs Performance? While I agree that there are better receivers out there for $550, are there that many out there better for $200?
