The Bianchi Strada comes to mind, at least if they still make it. Comes in a 44cm. Kinda heavy (just sold mine), but it's good old steel so going to be more comfortable than an aluminum bike.

The Torino and Monza look similar to the Specialized Vita.

Trek's 7.X series is also similar to the Vita. Here's the 7.3 FX WSD.
