The Wright Brothers Cycles wheelbuilding class in Fremont is fast approaching, and I haven't decided on hubs for my wheels.  New or used?  Expensive or inexpensive?  Servicable or disposable bearings?  There's 6 choices already.  Then, consider if the bike should be all serviceable bearings, or if it could have serviceable wheels and a non-serviceable bottom bracket?  I have Shimano Ultegra hubs with serviceable cup-and-cone bearings, and I like those.  The Campagnolo BB I just bought from a guy on Craigslist would make the bike's bearings all serviceable, but mixing Shimano and Campagnolo? That's not the orderly setup I need.  Is this telling me something about myself?  This is what obsession looks like.
