Very good value: strong, good hubs. Not particularly light but the '06 version is significantly lighter than the '05 and previous versions. The only drawback with Campy wheels (and this is true for other models, too) is the difficulty in mounting tires (espcially new ones, and espcially Michelin).
I think all of Campy's wheels can be bought with a Shimano compatible freehub. I sort of recall that Camply's Record level wheels do not use aluminum for the Shimano freehub material so they are a little heavier than the Campy freehub; this may have changed recently.
