TT is probably the favorite around here. I don't like the stem and levers on the Messenger, but those are easily replaced.

More expensive bikes are simply shwag. I'm not saying you shouldn't get one; it's a lot of fun to own a pretty green Bianchi or whatever else suits your tastes. Functionally though, a cheaper bike (like in this case) will be perfectly fine.
