You can buy 3/32 chains at any department store.
However, after years of just using the cheapest chain I could find, I broke the last Bell branded chain twice in the first 2 days I had it mounted, so I moved over to the HG-73 9s chain as my standard chain for just about everything.

Maybe the HG50 or HG71???? But, the 73 seems to work fine for me.
