Look for a good deal on 7710s. Mine were less than £100 BNIB on eBay. A 105 octalink BB will last forever and costs about £20.
Definitely get 75DDs if you can though. Lightest, stiffest, best looking cranks out there. Even cranks on there own (£210) come with a ceramic BB which can be swapped out for a £10 shimano jobbie when it dies.
I always thought the 75s are the stiffest but are you sure that the DD version is stiff enough, too?
And where to get them for 210? I just saw them for 299 including a Zen chainring..
These ones. They'll be stiffer than square taper 75s because of the external BB interface. I was lucky enough to get mine for £190 in the boxing day sale
