I'm sure you could find a good CRT for next to nothing, I often see
offices throwing out heaps of them, presumably because they've upgraded
to LCDs. You see a good many if you just go to the dump, probably quite
a few of which work perfectly.

They shoot electrons, which light up the phosphor coating wherever they
hit it.

You don't get residual electrons gummed up on the screen, but maybe the
phosphor on the screen degrades somehow.
