I ALWAYS check out the LBS first.

I have a good relationship with my LBS owner. I regularly --as in weekly-- buy components from spokes to headsets to tires. He's Shimano-based, so I hesitated to ask him to price a Campy BB last week. I need not have worried, as he got one for me for about the same price I'd have paid online with shipping considered.

The Campy BB's, I must add, are incredible. There is so little friction that the crank is able to rock back and forth like a pendulum for a good 10 seconds after a little push.
