If you really want a N810 and have patience, I would wait for Amazon or Buy.com to get more in stock... If they don't get more by the middle of July, I would then look to get one off of EBay... My gut tells me they will get more in stock. The sales channels still have to be swimming with these things. Woot hasn't even sold these yet...

I personally think the best "bang for the buck" is to buy a N800 off of Ebay.

There are a few buy-it-now N800's for $110 shipped (and no tax!!!). One includes a SD card...

If you watch the auctions carefully over a months time, you might even get one in the $90-$100 range. (I wouldn't pay more than $110 shipped)
