Actually, I posted up the redditor's ebay page for these, but he hadn't gotten any more of them made. I haven't followed up since.

As far as wearing the ring, I've never found it uncomfortable except for the fact that I don't normally wear jewelry or rings, so I only wear it once in a while. It looks like things would get trapped in the gears, but it doesn't, since there is a good amount of space between the gears to keep that kind of thing from happening. I've been very happy with it.

I don't know where you can get them for less than $165 now. :-\ Good luck though, they're sweet.
