Why? I've never seen any anywhere and it is pretty pointless. The cheaper ones are just a handheld meter with 230V instead of batteries, the more expensive ones have worse specification than a decent Fluke 4 digit handheld. You get a bench meter for the specification, trust and the calibration label. You get none of those from china.
If you dont have the budget, just buy a used one.
Why ? Because I though it was a good idea.
It's not about the money.
Fluke 77 the first 4 digit I found on Google £289 +vat
Rigol DM3058E £307+vat
Haven't read all the specs for either yet.
I've tried to buy older ones before but failed.
Perhaps that's because of the collectors.
btw The Fluke multimeters I owned many moons ago didn't last a long time because of the crappy LCD displays.
