School has an
ETC Express 250. We loves it...although at times it would be nice to have a 48/96 because it's so intuitive. Using the 250, all the cues have to be prerecorded, and it makes on-the-fly lighting rather difficult, especially with only 24 submasters.
And in practice, we generally use only about 160 channels out of our 250; a few more when we hang specials. The 192 channels of the 48/96 would probably be sufficient for our purposes.
