Looks to be a very interesting idea. In fact, I do want one. Buuuuut, I'd have to wonder with those prices for the full models and DIY kits if he is not overcharging by several hundred dollars. True, you're buying a piece of tech for its look and feel more than functionality, but as a guy who's actually bought, played with, and used old style typewriter, $700 is a bit much for anyone.
Could any enthusiasts (I consider myself an amateur) weigh in?
Looks like for your money you get a typewriter (presumably refurbished), a display and the electronics. As you noted, he sells a DIY kit if you want to provide your own screen and typewriter (with an estimated assembly/install time of 6-7 hours for an experienced person.
Actually sounds like a fair price to me. But perhaps you are used to getting your electronics assembled overseas on a massive scale by (essentially) slave labour.
Display? No. Those are iPads in the Etsy store. The typewriters are essentially USB keyboards. For $600-$800 you get an old typewriter and an pre-wired-up Arduino board. You're paying for the integration of this http://www.etsy.com/listing/62642931/diy-usb-typewriter-conv... into the typewriter.
http://www.etsy.com/listing/82254797/usb-typewriter-computer... I own this exact typewriter. I bought it a few years ago for $20. Now, if you have the money to spend, perhaps for a gift, and you don't feel confident that you can find a good typewriter and assemble it yourself, $700 might be worth it to you.
