I finally pulled the trigger and picked up a barely-used Trek 5500 OCLV frame/fork on eBay. Friendly discussions with the seller about other available parts he had resulted in a professionally-built bike with all Dura-Ace components, FSA compact crank, and Mavic Ksyrium SSC wheels. A bit more than my original budget with these high-end components, it should be a real looker and one sweet ride.
P.S. Now I might have to change my BF user name!
