I use it for two years. Before I had tried to acquire IMG Stage Line DMX-512 but that was nothing compared to Sunlite. What I love is the enormous amount of possibilities. It should be the same for rock concerts than for plays or musicals. The programming is simple. For beginners there are explanations for each menu (easy time, easy step, chase, noon, follow, etc ...) and there is a very fast editor effect for those who do not want to do the programming too complicated.
I blame the cons by 3D visualization to have delays when there are too many 3D objects other than fixtures.
The value for money is very, there's nothing to say. Especially there is a Sunlite Suite Basic Class for those who can not invest much.
Over time, I refer this choice without hesitation.
