>>3098283http://www.ebay.com/itm/332264526560Got mine today. Shutter count = 10. Not bad for $45. Add cap and battery for another $20 and I'm up and running. Not a GR, but a pretty interesting specimen of Ricoh's vision of the photography market. I love the bleak, almost Stalinist design of these things.
Now all I need is the A-16 module and viewfinder, which should run me roughly 10x what I've spent so far.
These things are fucking expensive if you want to get serious about them, but you can get started cheap.
GR IIs and IIIs don't cost all that much. GX200 is really cheap and is remarkably small once you get one in your hand.
