I'd sure like to know more about those gizmos.

I've seen those, and didn't suggest that because after looking at the
price those guys charge for them (I recall it was around $100?), I
really wondered if there wasn't at least something more than a voltage
divider needed (not sure why, tho). I can't seem to locate the link to
them, alas.
