I have a Fisher Big Sur (2002) with a worn Shimano BB-LP28 bottom bracket. It looks like the Shimano BB-LP28 is hard to come by. Is there an alternative to the Shimano BB-LP28? Would I have to replace the crank set if I were to upgrade and choose a different bottom bracket?

They aren't hard to find at all. Amazon has them for only $18. Look here: http://www.amazon.com/Shimano-BB-LP28-Alivio-Bottom-Bracket/dp/B000AKF4TW

The BB-LP28 is a very standard English threaded 113 mm spindle length cartridge bottom bracket nearly identical with the BB-UN26 but made for an MTB 73 mm bottom bracket shell instead of a road width 68 mm.
