I come from a time before DMM's existed, in any form! So my first was what could comically be called a plug and play meter! That is, it didn't even have a rotary range selector switch, you had to move the test lead to an appropriate range terminal on the front panel! This resulted in the inevitable, as it didn't even have fuse protection! So it was transformed to what looked like an extra from a Quatermass movie!
Sheckles were saved and I moved up to the big time with one of those big, really impressive looking (for the time!) Japanese TMK 100K ohm/volt things! Man, I was measuring things for the fun of it! That actually survived for some years and I cannot recall for the life of me what happened to it. Then I had a long break from electronics due to a polar change of career, so all my related stuff got boxed up and unused for 20 odd years.
Came a day when I was called upon to repair my dad's Hi-Fi amp, but no meter! Fortunately I did have some money by then so thought I would treat myself to a new fangled DMM!! Having no idea of what was good or bad, but strangely thinking that Fluke sounded like cheap tat, I resorted to what I knew would be good, Avo!! Namely, an M2007. This was a good move and it proved to be an excellent meter, I still have it, still works perfectly but is obviously a little left behind with what is available now.
Still didn't fully resume my interest in electrickery for another 15 or so years, but am now fortunate enough to be able to buy equipment on a whim, almost, so the collection of DMM's is in the hording category, and I did eventually realise that Fluke is quite good gear!
If I were asked what is my favourite, I can't name 1, but it's between my Fluke 289, Flir DM93 and Metrix 3293B, with the Metrix probably edging it. If budget were an issue, then my Brymen 869S would take it, no problem!
Oh, and to satisfy my yearning for the good old days, I have many Avo 8's, THE best analogue meter ever made!
