My 2 cents: I am a serious (at least alot of miles) and I've built up a serious madone mainly from parts I get here and there and money I get from sales of parts that don't fit. Its' the only way I can justify carbon frame, bars, crank, stem, Force drivetrain and zero gravity brakes for my 220# body at 20 mph. Often times I need info mostly on older DA and Campy stuff. When I go to the Vintage section I feel bad that I'm talking about a cool bike I want to part or sell rather than keep. I don't flip, parts bring more money than whole bikes nearly 100% of the time. But it would be nice to get comments from those out there that do similiar to what I do.
