The stuff you're watching is pretty high end, but I've noticed I can get good money for vintage track components no matter what they are right now. Even old Bramptom flip flop hubs, which were standard equipment on a Raleigh Gran Prix for a year or two... I sold a pair for over a hundred bucks a year back.
However, deals appear. Nashbar sold off a bunch of house brand track hubs a while back, basically rebadged formulas. Decent hubs. According to the one I just picked up (I ordered a few) I paid 15.29 per hub. So if you can be patient, do so. I also just picked up some new rims for them for 9.99; you gotta love Nashbar.
