Looking for a very small, simple, panel mount DVM. I've looked all over
eBay and Amazon and haven't found anything that suits my needs.

I can find plenty of LED versions, but they likely won't be satisfactory in
bright sunlight, and all the LCD meters I can find are huge. Something on
the order of 1/2 inch high by 1 1/2 inches wide, by 1/4 inch thick, that
could simply be gluded to the surface of the panel with a small hole to feed
the wires through would be ideal.

Just like OAT, I like to know my current power situation without fiddling
with the 302.
