This is an open ended question, and it's been lightly covered in Triathlete magazine, but I thought I'd get the forumers opinions.
I would go with the Cervelo Dual, full Ultegra components, including drivetrian, Aero Profile, internal cabeling, adjustable seat angle, nice set of wheels to at 1499$.
Trek Equinox 7 is nice too, and has always had a good show in price-to-quality I think. Trek is a mix of 105/Ultegra parts I think, along with many good Bontrager parts.
...Am I the only one that thinks the QR Kilo could quite possibly have the ugliest paint job possible?
Hopefully I haven't targeted myself to flaming in my first post in this thread.
