They were running a promotion where they were selling their initial supply for $850 (plus shipping from europe) for a while. I doubt there are any left cause that was months ago.
And last I heard, they weren't going to be available in the US after the initial supply was sold. Things could have changed, but that was the situation a few months ago......
