The reason I'm skeptical is that the mag compass also works fine for
holding heading in smooth air with very shallow turns: it doesn't go
to hell in a handbasket until the air gets rough, precisely the same
time the update lag in a handheld GPS could potentially also make it
difficult to use. That's why I'm interested in hearing from people
who've used it successfully in rough air, preferably at night (where
there are fewer visual cues like shadows moving over the panel).

And that's why I'm looking for a device that acts - effectively - as a
backup AI.

I saw a couple of devices at the Expo. Both were "boxes" that plugged into
different "computers". One was a large box that plugged into what I think
was and Ipaq, and one was a small box that plugged into a "Cheeta" portable
MFD device.

I really liked the Cheeta, but I think it was the most expensive of the
solutions I saw.

Anyone have other thoughts about this?

What was the price of a panel-mounted electric AI? 4K? I wonder if I could
get the club to consider such an investment on our aircraft.
