I'm gonna pick up a Samsung HDTV "monitor" of 23" and be a happy-camper with that one as it will have inputs for all my retro stuff, plus that it is 50Hz compatible. And it costs next to nothing...oh, and it has a tuner aswell -- which I ironically won't use ;-)
What model are you talking about? P2370HD or similar models? The specs say that it doesn't support 50hz through VGA/DVI, but only through the video-inputs (Component, HDMI, SCART).
Sometimes they will still do 50hz even if the specs say something like 56-82hz, but I'll have to wait till I get my MCC-216 to test it.
If not, I am thinking about a VGA-to-Component transcoder (without scaling and additional video processing) to fix that.
