Right now I'm leaning toward waiting until next year, or at least until 2011 models are out.
Im hoping a couple of things come together in that time frame: 1) Cervelo comes out with a Di2 internally routed frame (I like Cervelos, and my LBS just started carrying them); 2) Metrigear gets the Vector, pedal based, power meter to market ( so I don't have to take the DA crank off), and 3) maybe a bit of a price drop.
