Well, you want a true meter (actually measures and displays the
resistance) rather than a 'go/no go' tester that just says if something
is safe to use or not.
THe most important thing is probably the test voltage. You want to do the
tests at at least tiwce the normal working voltage of the unit (so at
least 500V in the UK). The better testers have the following :
Selectable test voltages (often 100V, 250V, 500V, 1000V). Very useful.
One thing to watch out for is the insulation class you are testing....
Running a 1000v test on insulation rated for 600v isn't the best thing in
the world for it.

Second-hand meggers are not hard to find in the UK,
and are not that
expensive (I paid \pounds 25.00 for an insulation tester, not Megger
brand, but well built, and with selectable test voltages, etc).
What would you suggest I look for in a tester? I've been thinking about
