Good choice on the cross check. Anything with a steel frame that would fit a 35c tire and up, and braze-ons would work so long as the components are good and size is correct. It really just boils down taste and if the bike fits you after that. That is a very nice commuter. I was going to suggest the nashbar touring bike, it is 699 and comes with 105 shifters. I have been eyeing that bike for long distance touring.
