Thanks for the discussion! I'm definitely getting the 720, and y'all confirmed my decision. I think it's going to be an excellent tourer, even if I never fully load it down. It'll also make a nice commuter.
The model number actually places its manufacture date as August 1984. I was able to open the brochure on the Vintage Trek site, and it appears that all of their tourers that year were made from Reynolds 531. Touring models available in 1984 were the 420, 420L, 520, and 720. I wish that Trek hadn't reused the 720 model number - it makes for some confusion in discussions.
I'm going to keep an eye out for a cheaper 520, probably. I think the seller wants a bit too much for it, and he decided to list it on eBay. I'll see what it goes for; maybe I'll jump in and get it after all!
