Pretty much any full cromoly frame with butted tubing is going to be equal in quality. The 412 is at the lower end of the Trek product line, which is somewhat misleading as they didn't make any bottom end road bikes back then, while most of their competitors did. But any mid grade or better LBS bike from that era is going to be comparable in weight, component quality, and more. So keep an eye out for a bike that fits and pounce when you find one.
Tange 2 is pretty good IMHO.
