I don't think typical hobbyist is interested in mains voltage at all.

Almost every beginner who gets a scope wants to "look at the mains waveform" as the first thing out of the box. Don't ask me why. I assume when they get a meter that's the first thing they do, they jam the leads into the wall.

I think you're right.  It's an immediate source of a sine wave (more or less) and the value should be pretty well known.

Threads start up here all the time about testing mains with some piece of new test equipment. 

I maintain that using a DMM on mains is a waste of digits.  A solenoid style tester is my favorite because I just need to know the order of magnitude of the voltage (120,{208-240-277},480) and, since there isn't anything I can do about the 3rd decimal place of line voltage, there really isn't much point in measuring it.  The voltage is either present and in one of those 3 bins or it isn't.

You can tell the voltage level with a solenoid style tester by how hard it jumps in your hand and how much it vibrates.  Also by the arc when you remove a probe.  This is close enough!  With this style tester, I don't have to take my eyes off the probes (and what I'm probing) just to hang by my knees trying to read the DMM.

Maybe I spent too much time working on industrial automation.  Way back when...  Side issue:  My issued Simpson 260 circa 1969 didn't even have a CAT rating, yet I'm still here!

I recommend Aneng 8009 which I use and it is really nice for mere 30$.

The 8002 and 8008 are great value if $30 is took high for your budget.  the 8002 is sub $20, and is built pretty well, and measures most of what you need to measure.
