No. I use the frequency counter on my UT61E a lot. It's actually good to about 30MHz if you buffer it with something with some reverse isolation.

Oh, I missed that. Thanks.

Then you can get the UT61E and another which is safe for mains eg Daves BM235
It is a good idea to have multiple meters, eg check strange readings with 2nd meter

Yes, that's certainly an option. Or a good and safety-approved "voltage tester" for the simple AC household voltage stuff (checking if a connection is live or not).
I do prefer having "all in one" type devices though (gear tends to pile up), so a multimeter with all the features I need including good safety specs would be ideal.
I had a look at Amprobe's offerings (AM-510, 520, 530, 540 etc.) again (from what I've heard they're the budget alternatives from Fluke) as I expect them to at least meet safety standards, but from what I've read in these forums they're a mixed bag, so I really don't know.
The big question is what kind of features am I looking for?
I'm not a very advanced electronics hobbyist ("intermediate" i would say) and besides the usual voltage/current/resistance/capacitance I need a good, responsive continuity tester, the ability to test LEDs and a frequency counter (not sure about the range though, but for audio and some digital electronics). It doesn't have to be super accurate (as in a voltage reading of e.g. 1.203785198 V), but hopefully not something that drifts too much within a year or too (I hear calibration is pretty expensive, not worth it for meters in this price range) and built well (I prefer paying a bit more for something that lasts than going for bargain basement stuff, but then again not pay a whole lot for features I don't need).

If you only want 1 meter and it must have features, the Bryman B867 is probably the best fit though I do not know what freq range it has. I do not have any Bryman DMMs myself but everyone else in this forum speak highly of them.
It is 3/4 times the price of the UT61E. The appeal of the UT61E is the price verses the resolution and accuracy.
Write down what you are looking for in a DMM, rank them in order. This will help you decide which meter best fits your needs.
Loboscope:
If you only want to check "simple AC household voltage stuff (checking if a connection is live or not)", you should use an UT61E (the GS-version) without risk. The "CAT"-categories will have a meaning* and with "simple AC household voltage stuff (checking if a connection is live or not)" you should stay completely in the CAT-III environment. But you should not test at the busbar and never at all behind it with the 61E!
But if you feel unsafe with the UT61E (GS), I could recommend the Benning-testers for electricians for testing mains. For example the more simple but very useful "Benning Dutest 050156" (but it is also only rated CAT-III 300V) or the more safe "Benning Duspol 050261" which is also not expensive but rated CAT-III 1000V / CAT-IV 600V. With a Duspol you can also test at the busbar.
Bennig Duspol is a kind of ´standard´-meter for electricians and all I can say is, that you can trust their CAT-safety-specifications.
