Along the same lines, does anybody know of a current meter that doesn't
cost a bunch?  Ideally something like a clamp-on ammeter that can handle
20A.  I'd like to monitor the current on a bunch of circuits without
having to spend much money (right now, I just periodically use a
hand-held clamp-on ammeter to see the "instant" current on each wire).

I don't speak for anybody but myself - that's enough trouble.
