I am alone in my unbridled enthusiasm, but i have a local shop that supports my habit and the guys' there are really pumped on the nicer vintage stuff.
being a collge town, the shop sees vintage steel almost daily though as college kids still routinely keep recycling 30 and 40y/o peugeots and other cool old bike. Saw a nice Kabuki on the rack there recently in pristine condition- wasnt high end at all, but i just liked seeing it getting new cables and tires as it signified it was getting some use still
but their main business is new carbon on the high end although the owner confided the margins are much better by percentage on low and mid range bikes than the trick stuff
