I am going with Vo2 on this one.
I have a Trek WSD and I LOVE IT! It comes in smaller sizes (mine is a 43), it has a shorter crank for those not so long legs, it also came with Mavic 650 wheels, and a vented Bontrager seat. I think you can change out the wheels, if you like 700s. It has all Ultegra/Tiagra components. Mine is a 2000 model (red, white, and black). I paid $1100 for it. (It didn't come with clipless pedals, though..FYI)
So, cost is variable. The newest WSD (metallic baby blue and white) that had a similar build was retailing $1600, last time I saw. Of course, if they have something special out there with DureAce components, clipless pedals, HED wheel, tricked out aeros, etc...then, you are paying the cost of those components, which will easily double the price of the bike.
This may give you a gauge for what is out there, so you don't get ripped off. Hope that helps!
