I transferred old parts from my commuter to my LHT when i built it up but I acquired parts over time with the idea of buying a new frame. If it were me I would be patient and shop ebay or Jenson USA for some last years model/closeouts and have the wheels built up at the LBS.

I picked up an LX crank @ Jenson cheaper that my buddy who owns a bike shop could get it for...he bought one for his LHT also.
