Having at least a 5 digit volt meter is really handy for finding
shorted components on a complex board ( note I said volt
meter and not ohm meter ).
I have a method that works, even on shorts between ground
and power planes. It locates the exact spot of the short.

Umm...does a 10-digit DMM exist? I have an 8.5-digit DMM (HP 3458A)
and it itself is quite a significant feat of engineering.
Probably not... Being able to resolve 1uV in 10kV would be pretty
amazing :-).
But that doens't mean I can't want one :-) Actually an 8.5 digit DMM
would be nice (or even a 6.5 digit one).
