Colin,
I'd caution against using the grounding of the electrical outlets as a
station ground. I lived in a house where the electrical ground of the
outlets had 150 volts which I measured between it and a stainless steel
counter in the kitchen. It turned out that the house's electrical system
wasn't grounded to anything in the known universe.
