For those wondering (envious), its a 56cm and I picked it up at the W&S in Hales Corners, WI. I'm 6'1" but with a short torso so the medium-sized frames fit me pretty well.

I'm glad to get some affirmation of a good buy. I hadn't been in the bike scene for a while and didn't know too much about current pricing. I'm just now realizing that these old steel bikes have a cult following by all ranges of cyclists. Unfortunately, I think my dad put a Schwinn World Traveler and another steel bike in the muni dump when I was a teen.

FWIW, about 14 years ago I was at the same Wheel & Sprocket and found my 1988 Trek 1200 for $250 or so. Sometimes they get trades I guess. Sadly, I got my drivers license about the same time as my 1200 and didn't ride it very much until this summer.
