Need a source for composite monitors

[lombardi@bldrdoc.gov (Michael Lombardi)]

Hi,

	I still have about 40 Apple IIe computers running as data 
acquisition systems at remote field sites and need a source for composite
video monitors.  All the suppliers I know of that used to sell the
cheap amber or green screens no longer make them (Apple, Zuckerman,
Magnavox, Goldstar, Tandy, Casper, Zenith, Franklin, Amdek, to name a few we
used to buy from when we had a lot more Apples running). 

	The last time source I knew of was Koyo.  They made a black and
white monitor that ham radio catalogs sold for use with the RTTY decoders.
However, apparently Koyo stopped making them, too.  Does anyone know of
a source?  I know I can use TV sets that have video inputs, but is there
a industrial type composite monitor out there?  I know I still see
composite monitors at fast food restaurants and in retail stores as 
surveillance screens.  Anyone know of a source?

Thanks,

Mike Lombardi
