Prodigy is only 6 sources if you use the wizard/SB. The true limiting factor on Prodigy is that it only has 5 IR ports. But soon that factor will be eliminated when the Prodigys can talk to each other natively(as opposed to currently where they can but its a 'hack')

Crestron has a wide enough product line that you can mix and match from for projects ranging in size from your Living room, to the Dallas Cowboys Stadium.

Now there WILL be lots of learning involved, from learning the core products youll use all the time, to learning the rest of the line, to how to program it all.

HAVE FUN!
