Hey CJ, great to hear from you. Actually, C4 stuff doesn't have to be expensive. It really depends on what you want to do. For a theater you really only need a single controller. Of course, if you want to start adding all the other goodies (lighting, multi-zone audio, HVAC, security, etc...) it can start adding up, but the basics really aren't all that expensive. I can put you in touch with my dealer if you're interested.
