It's interesting that no one does. Between the various retro-gaming and computing crowds one would think there's enough of a market for CRTs that at least one company would still be making them.
Well, most CRTs had mediocre image quality and people today remember a only the best of them (Sony, LG) which limits options and even then AFAIK it isn't exactly easy to make and distribute them which means a new CRT of good quality will cost a lot (in the four digit category). Also consider that it is already impossible to find OLED PC monitors and OLED panels are still is mass production so the machinery is there (CRT production machinery is probably either rotting or gone).
But yeah, if there was a brand new one i'd buy it without much thought.
