Canyoneagle, Ribble is doing 10% off right now, and it is cheaper to piece out than buy a full groupset with their Campy pricing. Total Cycling has a nice pool of UT cranks at decent prices, but all their other pieces are higher price than Ribble, even without the 10%.

If I did it again, I would get a UT crank. As thirdgenbird says, the puller is $60, but the crank adapter is another $60. I have not had the UT shifters, but have no complaints with my PT ones. I am crazy about my Centaur group, and avoided all the 11 speed chain tool BS.

I know the prices because I am contemplating sneaking another Centaur groupset, with a crank from Total Cycling, past the War Dept (my wife), just to have it for next winter's build, whatever that may be. The Nashbar retro was my fix for this winter, even though the bug seems to have not gone away.
