Another bike I'd add to your list is the Bianchi San Jose. It's a great bike for long distance riding. Canti brakes, lot's of clearance for just about any tires with fenders if that's important.

I don't have a San Jose, but I do have a Volpe which is the same frame but with horizontal dropouts instead of track ends. I converted my Volpe to single speed a while back and I've since ridden many rides of 70+ miles and a couple centuries. I've never had a more comfortable bike.
