>> What espresso machines actually use electrical conductivity of water to
measure water levels? is this a real concern? This seems a terrible way to
do it, when buoyancy (or a number of other possibilities) works so well? Why
would you use this?

Virtually every (every one I know of and I know many quite well) commercial
and prosumer espresso machine made with a steam boiler. Simple open and
closing of circuit via conductivity cheap and effective way of doing it. The
fact that espresso shots pulled with a modest mineral content in the water
taste livelier as judged by countless palates for countless years makes it
all work harmoniously.

Ultimately the quest for Koffee Nirvana is a solitary path. To know I must
first not know. And in knowing know I know not. Each Personal enlightenment
found exploring the many divergent foot steps of Those who have gone before.
