Wild that literally nobody makes these things anymore.

20 years ago they were everywhere, $100.

Now there's no factories left. All of the high voltage electronics are kind of bespoke and there aren't really supply chains for them anymore, but you COULD make them again.

The real kicker is the tube, the color mask and phosphor coating is a disaster. And what's more, the machines that made them are now archaic. Even if you were able to get one, keeping it maintained and working properly is a skill unto itself. Generally production engineers will always build new lines using only current era (CNC) machines for which the spare parts and knowhow are widely available.

This is an important little lesson that technological capabilities are not to be taken for granted. 20 years is long enough for a technology to really basically just vanish and once it's gone, you would need to go through a whole new R&D process if you ever wanted to bring it back.
@cjd I've got a point plotter hidden away with a P15 phosphor. It has a fall (decay) time of 0.05 milliseconds to 0.1% of max luminance, and falls to 10% luminance in 0.003 milliseconds.

CRTs are still used in labs that study vision, since you can't get that sort of response time on an LCD display, and the interval at which pixels refresh are much more predictable when you're dealing with a single electron beam.
