+1. I have five Campy 10-speed bikes, all with Wippermann Connex chains. Plenty strong, easy removal, sweet shifting, and way cheaper than the Campy equivalent. Oh, look, they're on sale for $30 at comp cyclist for the plain steel. Looks like Jenson has some deals, too. I use the nickel steel (10S8 model +$10). Prices up to $100+ for full stainless.
