Valuable tool for electrical fault finding.
You can pay a lot of a multimeter, or very little.
The cheaper unbranded ones tend to be a little temperamental so we've gone for one with a brand you've heard of rather than the really cheap "generic" meters on sale elsewhere.
So... a sensibly priced branded meter which will do most tests you'd need to do.
