Well the Eos is even more recent the the congo.... ;-)
You're right about moving lights on an Express though - infuriating - an Expression 3 (or 2x) that has
encoders - less so- but still not exactly a breeze.... especially compared to a console that is set up to do movers - like an EOS, Congo and the like. (Again there are other manufacturers out there that do nice products as well.)
But you are absolutely right in that they do need to take a look at the control situation and budget accordingly...
I will be very interested to see what s/he says that they already have for that...
