Original thread on Mobileread is
here.
From which, I found that the manufacturer site is
here, and appears to be still up.
The manufacturer site lists its Taobao shop as
here, but it is only selling accessories, not the reader itself (may be out-of-production). Searching Taobao, turns up two sellers:
here &
here. This does not however necessarily mean that they are still available for sale (it is quite common to see listings on Taobao for items that turn out to be no longer available).
Hope this is of some help.
