Alright, so I'm in a bind. I have been very slowly building up my old Raleigh frame to a SS/FG. Just got a Campy BB, and need a crankset desparetely. But, at a bike swap the other day the owner of my LBS was selling some Campy crank arms for $40. They are chrome, and won't work on my Raleigh, but will DEFINITELY be perfect for a future vintage build I want to do.

Anyway, that's what I'm having trouble with, get a crankset I can use now, or get one I know will be perfect for a future build later. I feel like I would never be able to get a deal on campy arms like that again, but could be wrong. What would you do!? Just need someone to kick my butt and tell me what to do haha. Thanks guys.
