Well, I do have an RCA WV-38A with 5 kV ranges, but I virtually never need
any of that. About the highest I ever go on a regular basis is the 200 volt
line on a CRT set or the Vs voltage in a plasma.
I might just pick up a Simpson of some variety or other though. The 260 XLPM
looks pretty good - I like the extra ranges compared to a regular 260 and I
must confess that between my advancing old age and laziness from using a DMM
the past 20 years, simple precautions I learned in tech school need to be
relearned. The other day I inadvertently put my Fluke 8800A probes across a
50 volt DC source while on a 200 ohm resistance setting. Didn't seem to
damage it, but boy, I sure gotta watch that stuff. Hopefully the relay
protection on the Simpson would prevent damage from any such stupidity.

The 260 XLPM is a good choice but the 8P does have overload protect
also and might be a few bucks cheaper.
I learned on my 260 but other than having that bit of nostalgic value
it really doesn't cut it like my old Fluke 77 does. I still do use it
though when working on tube amps for monitoring different critical
voltages.

Only on extra low voltage, I hope? ;-)
Extra low? Never had a standard banana type arc or cause a problem this way,
Website specs would suggest that fully insulated ones are good to 3.5kV RMS
