I've used (and use) America 6 and 7 speed with Campag Syncro index levers, and have not had any problems. I use period Regina chains, including the hollow pin ones. There's a Regina Syncro 90, which I also use, but it doesn't work any better than the America for me.
I've not tried it with Shimano, but I don't see why it wouldn't work.

Sorry, I don't have any for sale though...
