Hello Jakub, and welcome to the community!
I'm sorry to hear that you didn't get much use out of your TouchStream, but it's good that you didn't just throw it away.
You might be aware that the devices that used to cost around $400 new, now sell as used for a lot more. The reason of course is that they are very rare and much desired by the few remaining users. In the last few years, I've seen auctions on eBay for TouchStream keyboards that ended anywhere between $500 and $1500 depending on layout, condition, and simple auction luck.
To sell your TouchStream, you could post a message in our "Marketplace
" forum or even better create an eBay auction and then post a link to that auction in our marketplace. Be sure to describe the device's current condition and include a photo. If you could hook it up to a computer and test the sensors using the FingerWorks software, that would be an additional selling point. If you do put up an eBay auction, I would be grateful if you could include a link to http://fingerfans.dreamhosters.com/
in the description.
I'd be interested, as would several other community members - and probably a bunch of eBay people who don't know about this community yet.
