$450 is too much in my opinion. Keep in mind, the C-Record cranks are identical to the current Campy track cranks, other than the logo. Actually, I think the newer ones use a hex crank bolt rather than a 14mm w/dustcap, but still. Those differences are minute and definitely not worth paying a premium for.

I think I paid $250 for the last set I bought. That included a chainring.
