My daily rider Centurion rocks Shimagnolo. Campy shifters are rebuildable; Shimano derailleurs are disposable. Shiftmate in between. Also runs Shimano cranks and Campy brakes, but the former is OE and the latter was a lucky buy on ebay.
I find the functionality of Shimagnolo fits well with that bike. I stripped the paint and had it powdercoated industrial clear. It has a strong green-bronze color, but you can see the brass around the lugs. This bike is about the beauty of functionality, and Shimagnolo fits that style perfectly.
