I have seen that one on taobao....ridiculous
if you're willing to deal with the hassles of buying on Taobao and using a fee based taobao agent, you can find 'em occasionally in that price range.
I say occasionally, because these devices are rare to begin with and the $315 TP GO's I've stumbled across on Taobao are generally in marginal condition - about 5 or 6 on a scale of 10. That net cost includes extra fees for the transfer agent and two sets of shipping fees, one from the seller to the transfer agent and another from the transfer agent to you, the buyer, located in the USA.
Average net cost is around $500 - $750 for one of these devices in decent condition.
Some ***** is stil trying to sell one for $1280 USD . She's had it listed for over two months, turning down two offers of $500 USD or so duiring that time frame. Supposedly it's condition is 9+ on a scale of 10.
Don't think she cares if she sells it or not. Probably won't at that price. She has a poor seller rating too.
