Skydog, you still don't get the point. If you really understood what merlinextralight posted, you would stop making off-handed comments and innuendos about ISIS standards based parts.

"due to ISIS' less-than-stellar reputation for durability" is absolute fallacy! The only factor that contributes to YOUR continued concerns about durability of ISIS-based parts is the MANUFACTURER'S PROCESSES. If one makes a part to ISIS standards out of crap material, to hit a cheap price point, it will probably have some durability issues.

OP, if you want to try your hand at DIY repairs, I'd suggest you ask the LBS wrench who diagnosed your problem, what replacement he would use, buy it from him, and give the repair a try. You will probably have to obtain a BB tool suitable for the situation but that'll be part of your new DIY tool kit. Buying the BB from your LBS may cost you a bit more, but doing so will be more favorable to you when you start having questions/problems in the future. If you're up-front with the shop, they're more likely to help you learn and expand your repair skills. Besides, they stand to make more sales to you, parts and possibly tools, as you continue your DIY efforts.

The ground won't open up and swallow you if you buy locally instead of off the interwebs!
YMMV
