FWIW, a lot of current UK LCD (and I assume plasma) TVs have RGB inputs
at TV rates (15.625kHz horizonatal in the UK) onthe SCART socket. I
assume those will work with older computers expecting a TV-rate monitor,
although how good the quality would be I don't know.
But then I'm keeping a number of old CRT TV-rate-only monitors for my
classics too. My favourite is a delta-gun CRT unit made by Barco. It's
built like a tank, everything is on separate plug-in boards (3 separate
boards for the RGB amplifiers, a sync separatoe board, horizontal output,
EHT generator, horixontal defleciton, vertical deflectiuon and output,
convergence, and half a doze boards in the PSU -- and that's just the
ones I rememebr). Oh, and you get an exztender board clipped inside...
Fortunately I have the 'user' manual. It's got one page telling you how
to use the brightness and video gain controls. a few more pages on how
to rack-mount the unit. Then setup instructions. And finally many pages
of schematics, theory of operation and waveforms. That's the sort of user
manual I like :-)

2) It does something that modern monitors
don't (supports a particular
scan rate, for example)
I much agree. A few monitors out there support scan rates down to
15khz. These work on amigas and are highly sought after. The NEC 3D
was an example iirc. So check the specs before you trash them.
