I'll put in a good word for the Volpe. It seems like a great bike for a reasonable price, and I found it a comfortable and friendly ride.

(I got seduced into buying a much more expensive and less touring-friendly bike in the end... but the Volpe was almost my bike.)

Otherwise, I would just say to go with whatever feels best to you when you ride - I think all your choices are probably fine bikes, it's really going to come down to fit. (And making sure you have low enough gearing for hauling your stuff!)
