I have a bike with Galli Aero KL derailleurs. I had the same idea you did, setting up an early-mid 1980's Italian racer with something besides Campagnolo, just to be different. It has Ofmega CX cranks/HS, Miche pedals/hubs, Modolo brakes/levers, etc. All basically Campy copies although the HS is a different design. The derailleurs are really good-looking and work fine, actually everything works fine, I can't really tell the difference between this stuff and Campy NR/SR.
