Thanks for the info, I priced out a Shimano Ultegra cassette, rear derailleur, new chain and labor at my LBS (Trek Store). The total package price was over $200. I like to support a LBS but the part(s) prices were a bit over the top. A few people here have posted that a 32 tooth cog will "work" with the Shimano short cage derailleur (which I have). I may try buying a 32 cassette, a chain whip and the mechanism to turn the cassette with a wrench and see if I can get away with a short cage and a 32 on the rear.
