Obviously the only quantifiable differences here is the quality of the frame, and the shipping and service received. Dura-Ace is Dura-Ace, etc. I got turned on to these guys a couple of months ago, and what they offer seems to be quite nice at a very good price.
Actually, about the only negative I can find is that I really prefer to build my own bikes - not so much for the savings, but for the sheer enjoyment of doing it. Now, if they were just willing to sell the framesets . . . . . . . .
