I've graduated past the buying of cheap testers after dealing with an Extech that went wonky on me but showed no signs of wonkiness. I also don't carry any test tools that aren't TRMS rated except for my insulation tester. I don't need to test for energized circuits for safety on a regular basis, so I don't own a voltage tester (which is recommended over a DMM/clamp meter when the need for verification is there since with a voltage tester you can't accidentally set it to the wrong setting and mistake a reading).
On my tool pouch I carry a Hioki 3282 clamp meter. Small, accurate and handy, but no back light.
In the truck I also have a number of test tools from Agilent/Keysight which work with their Bluetooth system:
U1211A clamp meter
U1272A DMM
U1242A DMM
U1115A Wireless receiver
U1117A Bluetooth modules
as well as:
AEMC 1250N megohmmeter
The Keysight DMMs seem more accurate than my Hioki, but that's to be expected. They also work wirelessly up to 300 feet with the modules and receiver.
There are three more tools I'd like to add to my collection but can't afford it yet:
AEMC PEL datalogger
Tasco 42 circuit mapper
and a handheld oscilloscope.
I also have a few tools on my workbench at home:
Metrix MX24 DMM TRMS which I got on the AEMC website at a price I couldn't refuse.
Klein CL3100 hook meter for $15. How could I refuse that?

They still have them in stock for that price. Only downside is it isn't TRMS.
