FOr those who haven't heard of Uni-T its one of the more reputable meter makers in China. Uni-T is the ODM for Tenma, Voltcraft and a few others. Their lower price handheld meters seem to be the best value. That UT50A is not a bad meter for the price but in general the best bang for the buck from Uni-T is the UT61E. Note: NOT the A, B, C or D which are ENTIRELY unrelated meters, different IC, worse specs, completely different circuit boards. The UT61E can be had for around $55-$70 depending on where you look. The 61E is a 4.5 digit, 0.1% DC accuracy, Auto-Ranging, TrueRMS (though it can have issues with AC+DC combination signals), RS232 logging ability, that has excellent build quality overall. That being said, the input protection is not horrible but could be better. It does come with ceramic HRC fuses (though they are rated at 250V). I have one and can attest that it meets or beats its specs across the board. For example, my meter is about a year old it hits around 0.15% error on resistance on my 0.01% accuracy resistor.
As for other meter companies:
Besides Fluke, Agilent and Amprobe which all make great stuff.
Avoid any meter from Victor (typically model numbers VCxx or VCxxx) they are complete crap. Even the native Chinese hobbist won't touch Victor stuff. Uni-T and Mastech they will use, not Victor.
Mastech makes hundreds of meters (including they are the ODM for many other brands) so they vary wildly in quality.
Extech tends to be crap unfortunately, many of their meters suffer from bad to horrible QC. It used to be a recommended brand but way to many failures (and failures of the replacement or repaired device).
Brymen - There are some good values from this company (called Brymen Technology Group). Brymen is a Taiwanese mutlimeter manufacturer and they focus on safety in particular. So all of their meters tend to be some of the best safety wise. Also, Brymen is the ODM for Greenlee, but unlike most other ODMs the Greenlee models are 100% idential internally to their Brymen counterparts (externally the color is different). A good value model from Brymen is the BM-257 at around $135. It has phenomenal input protection and has nice accuracy. While the Brymen 869 (also known as the Greenlee DM-860A) is one of the best handheld multimeters period and cost in the $200-250 range retail. It rivals and or beats anything from Agilent and Fluke. 5 5/6 digit (500,000 count), crazy accurate, true CatIV 1000V input protection etc. As for the latter, the Fluke doesn't make anything rated higher than CatIII 1000V CatIV 600V.
Thats all I can think of right now, lol.
