Also you'll be waiting a long time for anything from Apex.

As has been suggested, try horizontal output NPN BJTs for big-screen,
projection and
HD television sets. Probably Japanese manufacturers/part numbers.

Also you could consider IGBTs from places such as http://www.irf.com, they are
easily available and cheap at 1200V. AFAIK, there is nothing available that
is PNP
and very high voltage, so review your output topologies if you need
push-pull.
