If you've already decided its a Fluke then the tried tested electronics model is the 87 V, that the 5th version of this series.
If you need it to be waterproof and rugged, its the 28-II.
I've had the 85 series one for over 20 years, so its likely you'll never have to buy another one for life. It was near $300 then, in 1980s dollars, so it cost me a lot. You'll buy lesser DMM later in your career that you won't mind destroying or losing or getting stolen, but when you need confidence and safety in measurement, I reach for the Fluke.
The next question is whether to buy new or used. Used one can be good deals if it wasn't used heavily in industrial electrical work. Its input overload protection circuits include MOVs, which wear out if exposed to high voltages, it depends on how high and how long the exposure lasted. If they were never exposed, they could last a lifetime. If and when they blow, the input will be dead so you'll know.
[edited corrected 289 should have been 28-II]
