I am building a dedicated home theater. I have had two different proposals for a control system -- Crestron and iPronto. I will be using it to control all of the electronics (projector -- Runco, Yamaha, Dwin or Sharp), Anthem processor and amp, Panasonic RP-91 DVD player, etc.) as well as a Grafick eye for lighting. In terms of functionality, what are the differences? Why should I select one over the other?
