There are several HP Jornada 720s for auction right now on eBay US. Do a search for seller Techsmartz. They have quite a few in their store and the J720 auctions are all starting at US$0.99.
Ahhh... so you were the one? Congratulations. Another just went for $94.50, today. Looks like we missed out on the $56 bargain, though. ;+) Just a reminder to anyone interested in these: drop a note in the eBay thread to let everyone know you're bidding on one. This way we don't trip over each other. Be sure to include a link or at least the item number.
