I need to replace my ageing multimeter so I had a look on line. Wherever I search all roads lead to Amazon and I refuse point blank absolutely to have anything to do with them on principle.
Can anyone recommend a multimeter? I need DC volts, amps, milliamps etc for automotive use. My meter is an ancient Draper and becoming unreliable.

I dare not post the reasons or I could be done for libel.
In addition I need ohms and circuit continuity facilities on the meter.

I bought this one recently (and the extra leads kit) - as you can see, I bought it through Amazon. I avoid them too if I can get something cheaper elsewhere, usually ebay, but in this case this was the best deal.

So that includes every multimeter ever made.

Could you be a little more precise? Smile

Some of the ones I've looked at on line don't have all the facilities.I want, DC volts to 24, amps milliamps, ohms, circuit continuity and rpm. I don't need AC but auto ranging is useful.

The only specialised measurement in your list is RPM. For that you need a tachometer function. There are some specialised automotive multimeters which have a pulse pickup that you connect to the LT side of the coil. Any multimeter with a frequency function can also do this, but you need to do a bit of maths to get the RPM value from the measured frequency.
If I have any weird ignition issues I just put a scope on it because it can display the ignition voltage rise time waveform which gives much more information than a simple tacho.
