Agreed.

I was thinking $1200 was a bit high for a (very) left-over Bianchi. I doubt they retailed for that back when they were new and time has passed them by so based on price I have to (reluctantly as well) say go with the Jamis.

Just to be a contrarian I'll say that if the price was better this wouldn't be so clear cut. I doubt the frame on the Jamis is any better than the Tange steel Bianchi and since you are used to down-tube shifters that isn't an issue. By the early 90s down-tube shifters were at their peak. Shimano 600 (Ultegra nowadays) was always good stuff and the Jamis isn't high-line enough to have the benefits of the better wheel technology that is definitely available today.

If it were a Columbus framed Bianchi...
