For the second week in a row, Barnes & Noble are offering a refurbished NookColor ebook reader for $189+shipping. You can find the deal on B&N's outlet page on Ebay. It comes with 1 year limited warranty and 90 days tech support.
I'd like to say that this is a good deal for the 7" ereader, but TBH I see it as the normal price for the refurbished units. They've dropped the price (it was $225) too often. If I were going to get a NookColor, I'd wait for the next time B&N dropped the price.
