My lowly 1987, 550 Bridgestone, picked up off of CList after it languished a couple months, the seller wanted about $200, then added or Gold or Silver in trade. I had a cache of Kennedy .50s in my closet not doing anything, so I got it for $17.50 in 1965-1970 (40% silver) Kennedys. Not too bad of shape, but some rust..FLORIDA! Seatpost took 10 days to break loose. Patience.
