A second Kindle was just listed on eBay with a minimum bid of $399 and a reserve price. There are no bids on it yet.

The seller says that the Kindle just arrived in the mail, so maybe the dearth of Kindles on eBay is a result of their not have yet (by and large) been delivered by Amazon.

It will be interesting to see how bids go for this Kindle. It has only a two-day auction period (as opposed to the other Kindle which still has nine days or so to go and already has a bid of $810).
