I'm the one with the Ruby Pro and Campy that Caligurl mentioned and I absolutely love my bike. There's a pretty torn up descent around here that on my old bike would feel like I was riding a jack hammer. My shoulders and neck would always be in pain when I hit the bottom. I went down that road on my test ride and the Ruby was so smooth, I thought they had finally repaved it. I actually rode back up to make sure that they hadn't.

My LBS was great about swapping out the parts. They put the Dura Ace parts on another new bike and credited me back the money. But know that it's not just the components that you'll need to swap out -- you'll need a different wheelset with Campy-compatible hubs. I decided to go ahead and put some fairly pricey Rolf Elans on the bike (~$850 with my discount). With the trade in credit, I paid about $800 more than I would have if I had left the bike with Shimano.

I hope that helps,

Susie
