Bikes: mid 1980s De Rosa SL, 1985 Tommasini Super Prestige all Campy SR, 1992 Paramount PDG Series 7, 1997 Lemond Zurich, 1998 Trek Y-foil, 2006 Schwinn Super Sport GS, 2006 Specialized Hardrock Sport
Ballpark: $200-250 for the frame ($300 tops if nearly immaculate). Complete bike in fully working condition: $400-500.
FYI, I own a 1979 Trek 510, which is similar, but built with Ishiwata 022 tubing, and as a result of fashion, is not worth as much (maybe $100-150 less than the 531 frame version), despite being the equivalent bike.
