I own 8002, 8008, ut61e, keithley 2000 and two GW121 meters. I do mostly low voltage "arduino" and some analog stuff.
ANEGs are cool, but I wasn't able to disable auto shutdown feature
I think it's best value for money. I have both, I like them, but shutdown is annoying. Also adjusting is not trivial.
UT61E is also good. I like it. Can also recommend. Easy to adjust, but accuracy and drift is so-so.
Of course none of them ideal, they have their own problems. I recommend buy good with with crocodile clips.
Concerning measuring mains, I think it's no problem if precautions are taken (I'm aware they don't meet claimed safety specs).
PS for a single meter I'd go for uni-t. But I suggest have at least two meters. Say, one uni-t and on aneg.
