Best handheld dmm, at any price?

Probably the illegitimate spawn of such and a room thermostate, conceived during full moon in a severely toxic landfill.
Fungus:
Somebody just posted a video in the 121GW thread that shows autoranging speed of the Hioki DT4282 vs. other meters.
It appears* to show that the Hioki is the fastest of the bunch, faster than a Fluke 87V.
(and much faster than a 121GW)
(*) Testing methodology is suspect - can you connect meters in parallel to measure resistance?
Synthtech:
Multimeters in parallel measuring resistance makes no sense to me.
bd139:
Most of the DMMs use a current source of some description and then measure the voltage across the resistor.
Apply superposition theorem/KCL and the answer is obvious :)
bd139:
Just to back up how bad this can get, here are two meters measuring the same resistor. The GDM-8341 is spot on and does not change if the Keysight one is connected or not. Resistor is a 1k 1/4W 5% carbon film jobby
