However, for the earth loop impedance tester I did go to eBay. Got a
nice Robin for 85 quid.

I got current model digital Seaward earth loop and RCD testers for 80-90
quid each, with brand new calibration certificate. I got a "Newlec 121"
insulation/continuity for 30 quid. Working, but not certificated, it appears
to be a rebadged BM121.

All the Newlec test gear is rebadged AVO Megger although the Newlec
ones are red now but still the same spec as the Megger meters.
