Personaly, I would look at the sea changers or enough scrollers to build a basic system first. As far as replacing your console, with as much shownet that you have in your space, you would be shooting yourself in the foot if you went with an
ETC console or any other manufactuers enless you buy a few nodes change everything into shownet on the input side.
Strand consoles run s4's just as well as anything else. Any movers you get at this point are not going to be all that useful because you simply won't have enough to do something besides the random special here or there. Look at the seachangers, maybe pick up an icue or a
right arm to pick up those random spotlight things. You don't want to use something that costs a lot to repair and buy new lamps for to light a podium for a meeting night after night. I would really look at the right arm, get a
DMX iris for it and throw a
scroller that you allready have in stock on the front. At least then you have a time saving thing as in setup an parts that are usable in other locations.
