In my opinion, there are lots of good chains, and like all things bicycling, more $$$ doesn't necessarily mean a better product, likely just one that's lighter and prettier. The chain is the weakest link (sorry, couldn't resist) on the bike, mechanically. Whatever you get/have, keep it lubed and monitor wear and condition.
Occasionally you hear a complaint about an SRAM powerlink breaking. I don't know anyone first-hand that has had it happen to them.
