Hi,
Just out of curiosity, does anybody really need the usb feature? After looking into it I think an O-scope is much better.
If you have to make a lot of measures to be recorded for documentation or similar, it may be helpful, but in all other situations, it's fairly useless.
My idea of quality in a DMM is not some kind of circus horse with all kind of gizmos, but a clean meter with just what's needed, i.e. V (AC and DC), A (AC and DC) and Ohm ranges and nothing else. Then it's useful for what it's for. That's why I got me a Fluke 77 for hand held jobs.
Leave all other functions to dedicated meters that can deliver good measurement ranges in their respective categories.
A Swiss Army Knife may seem useful with a complete toolkit, USB memory and what not, but it's not very handy if you just need to cut something (and neither if you need to fasten a screw, open a can of food or whatever).
The extras you get in DMM's, like frequency, inductance or capacitance ranges may sound all that, but they're severely limited compared to dedicated meters nd will just be clutter in daily use.
All that said, you won't make better circuits using the best of DMM's than with the cheapest $4..$5 meter, so you might wanna go for something entirely different, like other types of instruments, tools or perhaps a lab power supply.
