I now think that for $119 shipped, I'd rather buy this one:

It has a few small rubs on the sides, but otherwise looks very clean and well-cared for. (Having all four of the original cork "feet" is always a good sign.)
These are doing nothing but going up. I predict that by this time next year they'll be up around $200. F-ATs have already done that, and they were in this price range a year ago.
Nice. I think mine may be even a bit better than that one. My cord is way more shiny ;)
Gonna get rich! ;D
