Yeah, I was going to mention that, too. The shifters are totally rebuildable with Campy, where Shimano you replace them and use the old ones for fishing weights. Also, the cassettes can be customized, as each individual cog comes off seperately. I also like the cleaner look of the cable routing. Campy is spendy, though, and they don't support their older stuff. I have an 8 speed group on my daughter's bike and cassettes will become difficult to find, I'm sure.
