Surplus Center also has sprockets and other stuff cheaper than McMaster-Carr and MSC.
I have used the chain and links from Northern Tool and Surplus Center and it works fine. No failures at all. It is not Browning but doesn't cost as much either.
BTW: Nothern Tool is also a good place for wheels and sprockets. Look around in their Go-Cart parts section.
Also, don't forget a chain breaker like this:

It is an invaluable "special tool" for any FIRST tool box!
