I use two multimeters for general purpose use, including Tek/HP scopes...
I rather like Fluke 25s - built like a brick (can be used in explosive atmospheres!) and pleasingly accurate.
I also rather like Metrix MX67s, simply because they are so different and ergonomic when noodling around a circuit - the display is right in your hand, not somewhere off to the side. N.B. no current measurements. The ergonomics are obviously subjective, for example I don't like the pen-style handheld multimeters since the display digits are at the wrong angle.
Neither are new, both were widely used by the military, both can be found on fleabay at <<£200. Neither are true RMS but I would have thought that a CRT heater supply would be a sine wave in which case true RMS would offer no advantage.
I have a spare pristine (probably never used except for recent calibration) working Metrix MX67 that I can sell for £30. See below for a (somewhat contrived!) picture of the one I keep on my bench.
