I replaced my own bottom bracket! Ok well, first I destroyed the threads on the cranks meant to interface with the bottom bracket tool. Thus requiring a shop visit. And the shop, after consulting with the frame manufacturer, cut the destroyed cranks off with an angle grinder (and posted a video to their Facebook page - you don't usually see that many sparks in a bike shop). But hey, I now have a nice, let-the-pros-do-this-job souvenir (the wrecked cranks). And my bracket/bearings are creak-free and spinning quite nicely three years later.
