I need a cheap controller to tide me over until I can afford a nicer one. I've got a pair of technobeams and either a pair of Mac 250s or 4 trackspots. Is this board capable of doing some decent live programming on the fly? Or at least putting together a good show that can be adjusted very quickly in real time? Or, in the alternative, will I be upset that I wasted my money on this thing (at approx $270 after shipping)? I will probably be a bit embarrassed of using an Elation deck, but thats why they put us lighting guys in the back.
