Any reason to avoid FSA chains ?

I'm seeing some great deals on some 9-spd chains from FSA, and am wondering what the word on them is. I've always known FSA to be a good product, and the vendor is solid, but the deal is good enough that the old adage, "if it looks to good to be true" is springing to mind, so I figured I should make sure there aren't any issues with them. (I'd be getting a couple for a commuter/casual-exercise type bike, not a racing-sprinter, so the degree of stress on them would be minimal, but i'd want to avoid them if they're absolute junk).
