	I am taking your specifications literally, and am being primarily
guided by your 28-40 KHz horizontal scan rate.  That is the killer.  There
are no inexpensive raster scan color displays that will operate in that
frequency range.  I know - I have looked!  The least expensive monitor I
could find was a Conrac 7211RS19 which set us back about $ 3.9K a year ago.
The 7211 gives 1080 horizontal by 809 vertical pixels for a 1225 line
resolution.  That is more resolution than you asked for - and was also more
than we required.  However, we had some graphics hardware that would *only*
work at 31 KHz.
	There seems to be a whole order of magnitude price jump when one
goes that high in horizontal scan rate.  I am not certain why that is, since
the monitor circuitry is not that much more complex than that of NTSC monitors.
	If someone knows of a raster scan monitor meeting the above specs for
less than even $ 3K please let me know, too!
