there is a very nice-looking 51cm nishiki prestige listed on
craigslist in the bay area right now
http://www.craigslist.org/
(it's listed as a 51cm, but i'm willing to bet they measured to the bottom of the top-tube)
it's priced at $150, down from $200 when it was originally listed a few months ago, which seems like a pretty nice deal for a tange infinity frame.
(i'm not positive that this bike makes the time-line cut-off, if it doesn't, please accept my apologies).
no connection to seller.
