I just got a Specialized Allez, it is sweet! I rode a Giant but didn't like the fit and the Specialized had a smoother ride. I just got to ride it outside yesterday for a few miles and I love it. Sorry, I don't know much about the bikes in my area we can only get Trek, Specialized and Giant - in my price range anyway.
I am still getting used to the clip on pedals tho, I have used the straps for years. I really like the way you pedal with the clip ons, I can tell a big diffference, my knee used to hurt for the first several minutes on a ride but no hurting now! I did have some aching after my first ride but I figure that was b/c I wasn't using the proper muscles pre-clips.
