I am in the same boat as you Tom. I am working on an all Campy build and MUST have shiny silver hubs and rims. As mentioned you may have a hard time finding exactly what you want.
I put a WTB on Paceline and almost found what I wanted, most replies were either too used or just too many $$$. I ended up buying Campy hubs that will take 9/10/11 speed cassette and now can choose the rim I want. I'm not really considering weight, just aesthetics.

You might also consider these for a silver box rim> http://store.velo-orange.com/index.p...700c-rims.html
I haven't ridden them but they look pretty.
