I ship all my boards in ESD bags regardless of susceptibility. But that Bally rectifier board is the least ESD susceptible board available. Would take a pretty hefty hit to kill him off. The LED (if one of my boards) is probably the easiest zapped part on him.
When working on boards at home - I use one of these:

And bought some nice 3M wrist straps and a 3M wrist strap grounding monitor in a company auction.
