Stop in your LBS and just talk around with the staff as you drool over things. It's amazing what you find from the avid cyclists that work there even from their own stashes!! I found some vintage Campy stuff for my bike yesterday just talking to one of the guys there. He had the chain rings I need for my old 8 speed Chorus stuff that only 500 miles on it. Showed it to me too! Just ask around or chat about what you're doing. You'd be surprised what you find!
