In the US working units w/cables sell for about $600-$700. Ones with latest update go for as high as $1200. Its a shame but you would be lucky to get $200-$300 for it.

You may be better off selling it in parts. With the unit being bad the money is in the keys and adapters.

Dunno why they didnt just use a rechargable battery pack like they use in the modis in the solus. Alot of them were sent to the grave because of leaking battery issues.
