oh also if you want a sealed bottom bracket option, there are none...except for a phil wood. or a shimano un-72 with phil wood rings.
phil wood is like 100+, the un72+phil wood rings will cost you about 70 if i remember correctly, but just replacing the spindle and bearings will save you more money.

another option is taking it to get the french threads rethreaded. or the least favorable option, threadless bottom bracket.
