I use the GEO alt and an advantage with it is
that if you kill power
to the exciter lead it will stop the power output so you can shut it
down in the event of a voltage overrun.

East
Coast confirmed that the UltraMini works like that as well. After
seeing Mark's message, I called around, but the cheapest I could get
one was $135 + $35 core, and that was for a rebuilt unit. I just went
ahead and ordered a new alt from East Coast for $219.
Now,
the problem will be coming up with a double pulley. They said the
shaft was 15mm, and the normal size was 17mm, so finding a double
pulley might be tricky. If I can't make one work, then I'll have
to consider using just a single V belt, or trying to convert to a
serpentine belt. On one hand, a dual belt seems like it would be twice
as likely to keep the water pump running, but in reality, it's not. If
the outer belt comes off, the inner could remain, but if the inner
comes off, the outer belt will go with it. It's tough to say if it
really offers any redundancy, but it does offer more contact area on
the water pump pulley, which has a terrible geometry already.

Rusty, Racing Beat has a double pulley in aluminum and of a bit bigger
size than stock to reduce alternator RPM. Should fix everything in one
shot.
