Would like a new commuter, may have to wait until next year. Locally, I've been looking at the Vaya, Surly LHT disc, Redline Metro and a Jamis Bosanova. All bikes have disc brakes.
If the Bosanova had Avid BB7's, it would be perfect. I remember reading that choosing a bike should be based on frame first and components and wheels next. With this is mind, I guess it's a toss up between the Bosanova and the Vaya.

Good luck with whatever you decide.
