A new one from Noritake is $800, so that's a no-starter.

Any ideas how to pep up a fading VFD display?

it's the 19-segment alphanumeric type, one line, 20 characters.

Have you checked to see if it uses a standard interface? You may well be
able to get a cheap aftermarket display that will drop right in.
