Chroma key is not usually a function relegated to a separate device, but
is a part of the production switcher.  (The thing with all the lights
and levers and joysticks on it.)  You can pick up a small 8-channel one
with chroma key for about $3500, but you must also have cameras that
can sync to an external source, such as your Amiga.  If you don't you'll
also need a time base corrector, another $4000.

But have no fear!  The A-Squared folks have SOFTWARE that in conjunction
with their LIVE! board will do rudimentary chroma-key, and I beleive
Digital Creations (Makers of supergen) has something similar in the
works for their Living Color series.

Hope that helps,
