I use a multimeter occasionally. I used one to make a Headphone Amplifier kit a few years ago, and occasionally to test voltage on an AC or DC Adapter. 

I don't want to spend crazy money but something with a decent range of features, and is accurate.  I have the option to pick one up in the US if needed, but happy to buy in NZ. 

I know Fluke are the gold standard, but at the prices they charge, they should be. Probably couldn't justify that for the amount of use I get.
