Can't go wrong with the Fluke 87V. Diode test beep, Auto Hold/Touch Hold, always on backlight, perfect continuity tester, fast Peak Min/Max, super long battery life, the list goes on. If I could have only one meter, this would be it. For a second meter, maybe an 87III for the high res (1000 count) bar graph or an original series 88 for the Change Alert (no other meter has anything like it) and also the high res (2000 count) bar graph. Basically, the 80 series can't be beat.
