I used to have such an item; it worked very well; unfortunately, I don't
have all the details.  But here's what I have: it was a TV tuner for RGB
monitors.  Its retail price was something under $100, and it was made by
Taxan.  I used it with a Taxan RGB monitor that one could charitably call
"piss-poor" -- but as a TV, it was remarkably good.  My roommates and I used
to make fun of the old "Zenith beat Sony again?!?" ads --> "Taxan beat Sony
again??"

Anyway.  You asked for a composite --> RGB device.  I don't remember if the
Taxan device had a composite input, or was strictly an RF tuner.  It was
definitely cable-compatible.  If you were willing to put up with an
additional layer of degradation, you could wire up:

  composite source --> RF modulator --> RF-to-RGB tuner --> ST monitor

If you simply want to use the monitor as a TV, expect an excellent picture.

(I was unable to post this to comp.sys.atari.st: gorn doesn't get it and
inews won't buy it).
