The more I search for models listed in this thread, the more old BF threads come up with people asking he same question as me! There's certainly a lot of interest in this type of bike. As of now the Trek's still pique my interest the most. They had a lot of sport touring frames in the 80's that meet my qualifications, and if I avoid a cantilever braked 520, I should be able to find something quite affordable. The big bonus is that no one will cry if I bastardized it with new parts, since they aren't that rare. A 22.5" Elance with a 9spd 105/ultegra build and a brooks b17 would be about perfect.

Thanks for all the input!
