I have a Fluke 88 I bought when I still worked on car for a living. I bought it after I went to the GM electrical diagnosis class and on the first day the instructor picked it (a Fluck 87) up and dropped it saying it would be the last Multimeter you would buy. Needless to say I was sold. I bought the 88 because it could check RPM and dwell.
