I think prices are going to slowly and steadily increase for complete bikes, frames, parts and accessories. This goes for top-of-the-line racers all the way to all-arounders. I think there is a back-lash against exhorbitant prices and the superfluousness of brand-new gear that commands such prices.
Our sub-forum For The Love of Three Speeds should make it pretty clear that people are going more-and-more for vintage bikes. If you're talking 1950's-60's, prices are up. Sellers know that people are scouting these older bikes/parts.
Get yours now, before the prices increase, and moreover, supply dries up.
