I have written a article about high-end multimeters, it is a good starting point for people that want to get a very good multimeter, but they are not cheap (The cheapest one is probably a couple of 100 dollars)!

The meters included are: Benning MM12, Brymen 869s, Chauvin Arnoux CA 5293, EEVBlog 121GW, Fluke 87V Max, Fluke 289, Gossen MetraWatt MetraHit Energy, Gossen MetraWatt MetraHit PM Prime, Hioki DT4282, Keysight U1252B, Keysight U1272A, Keysight U1282A, Kyoritsu KEW1062, Metrix MTX3291, Sanwa PC7000, UNI-T UT181A
I have all the meters and may be able to answer questions about them.
