I'd get a cartridge style BB for Portland commuting, etc. Caged BBs might take the water too "personally"...plus cartridge BBs are pretty cheap to replace.

Sora Cranks 165mm - Harris Cyclery. A good friend has a set and they seem to fit the bill and then some. Not sure what BB he has lined up with them though...SKITBRAVIKING: Where be ya?

Those two combined should be reasonably priced for your wallet!
