Don't be afraid to hit up craigslists, I've seen some crazy good deals.

I just picked up an almost brand new set of black 75's with Sugino bottom bracket (the $100 one) for $140 total. Everything was pristine with just a tiniest of scuff marks on one crank arm (that you'll end up doing with a day of riding).

The owner bought the 75's and then came across a killer deal on the DD75's...so I lucked out.
