I just got a Bianchi Veloce, with a triple (gotta have my granny ring!), and I am very impressed with how light it is. It's a steel bike with a carbon fork. My DH (the bike guru of the family) advised me to stick with steel if possible, for the ride and for the fixability. He loves titanium too, but it is more pricey and not as easily repaired if need be. I saw that Salsa has a cool road frame that is steel also (I think it is called La Raza). There are quite a few nice steel bikes out there that are lightweight if you look around.
