Still very expensive. I only own an elCheapo multimeter, just good for
coarse measurements. If I have trouble at home where something better is
needed, I ask a friend who owns a measuring bridge and several
oscilloscopes etc., if I do a job and something is "really" broken, in
other words more than just a controlable voltage stabilizer needs to be
calibrated, I ask to give it to a workshop. IMO it's not only expensive
to own all the gear that sometimes is needed, it also takes too much
space. If equipment is seldom used, it tends to fail at the moment it's
needed. IMO an averaged audio engineer who does mixing, wiring and
repairs without a big fuss, doesn't need such gear.

OT: I would like to own a Hameg oscilloscope with the so called
"Komponententester" (translated perhaps something like "semiconductor
tester"). I wonder if there's any other company offering this.
