Honestly, at a highschool I would go with a very basic two-scene present board by
Leprecon or something similar with a memory board that allows them to also record and save cues. Why you might ask-- because this is going to be used by people just learning the trade and before you learn to run, you need to learn to crawl or walk. There is something so pure and earthy about
manual fades, crossfades, and learning to start off by doing more with less. Honestly, a monkey can create lighting cues on a fancy automated
console, but learning on a
manual board creates artists. They will have plenty of time to use and learn the latest and greatest automated consoles later in their career, but you can be doing them a disservice if they never get the basics. Just my 2 cents, and I'm sure many will disagree with me.
