As I prepare to purchase my new road bike (most likely a Specialized Roubaix Pro), I am trying to determine whether to buy the complete stock bike, or just the frame and fork and build it from there. I would prefer to build it since I would like to give Campy Record a try and don't really want the Dura Ace wheels or the Specialized seat or bars. What's the best price I can expect to find either the Campy Record or the Dura Ace 10 speed Groups for? If you have any great sources please share them.
