BobLab, I did a number of reviews of multimeters over the years (in portuguese - I link some of my reviews below).
As an absolute low cost I can recommend the
Richmeters RM113D, which is 6000 counts with TRMS, well built and compact. Next on the line with higher counts (20000) and a bit more features is the
Richmeters RM219 (also known as Aneng AN870), which is larger and reasonably built. Next in line would be the
UT61E, which features a decent bargraph and is more responsive than the other two (and it has one of the best capacitance meters) but it is more expensive and is being replaced by its newer generation UT61E+. I also tested the popular
UT139C (also Minipa ET-1649) and I thought it was a good and robust (with less features) alternative to the similarly priced UT61E, but some people reported it is electrically fragile.
Keep in mind these are not electrically robust, but for the occasional mains measurement should be absolutely fine - the only one that requires more attention is the RM113D, which shares the µA/mA input with the Volts. Otherwise, it is fine.
On my pipeline of reviews are the AstroAI M6KOR (Kaiweets HT118A) and a Greenlee DM200A (Brymen BM251S) that are proving their value on my current usage here in my bench.
Boa sorte!
