Search around... lots of people have had cheap eBay chains that wear out quickly (if you're lucky) or break.
I saw an eBay chain toss its o-rings and destroy itself in less than 400 miles on a friend's bike. That was a fun day...
Get a good chain. It's not worth risking broken engine cases or flaming death.
The "generic" Primary Drive and Parts Unlimited chains are OK if you're really caught short.
