Zero crossing detection is not needed at all if you don't wish to do dimmers with the SSR.

When I find a small and cheap zero-crossing detection circuit, it might be a good addition to enable lights dimming, when I already have the SSR's because of other reasons.

Sharp PC814 is one example, they cost around $0.15 each when purchased in lot.
