I know this thread is ancient now, but I purchased an eMate 300 in January of this year (2010) and got a great deal. I got a working eMate (dead battery...) with an ac adapter and stylus not to mention the memory upgrade for $30. I also purchased a wireless card for it, $10, that I still need to get working. I think the eMate might need a hinge fix in the near future as it seems to open a bit stiffly. Either way, very cool and definitely worth the $30 I paid for it. I think the memory upgrade might be NewerTech, but as the eMate reports 4MB of storage I'm guessing it's working at the moment.
