Jan and everyone, Shimano still sell simple pulleys with a non-floating top pulley and these are perfect for Campagnolo and other pre-indexed derailleurs. Cheap, too--I sell these to repair customers for $5/pair. Bullseye makes/made good pulleys but I used to mark them with a centerpunch for in/out and top/bottom--they wear just like plastic pulleys, and if you take them off to clean and don't reinstall them the same way, a chain will run really noisily on them.
