I own quite a few multimeters
so here is my experience
FK87V - that one is OK for electricians , it is doing only VERY, VERY basic staff, it is USELESS for several BASIC electronic mesurements which are needed even for simple repairs like FM tunner repair. If I would do something with car - I will take FK87V, but not for electronics, even a cheap Unit-y multimeter is sometime a better choice than FK87V. FK87V is also quite BAD with measuring LOW values like for small current.
U1242C - that one has only 10000 digits therefore useless for plenty of electronic tasks/repairs, even worst that FK87V.
Fluke 179/177 - that one is also for electricians, almost useless for electronics.
BM869S - that one is quite OK . I would only complain small rotary switch, which is hard to switch, strange location of bargraph at very, very botom anf not the best backlight. I take from my shelf something worst with meaurement than BW869S because this anoing rotary switch/backlight.
