7channel - I had Bitwise and it may be a good system but the implementation of it I received was spotty for all my gadgets, and then when I wanted to make adjustments to the way it functioned, the lack of responsiveness from the dealer I had gone with was very frustrating. In the end I didn't like Bitwise at all but I'm sure that is the outfit I was getting support from. If you think this is a direction you want to consider, let me know as I have a BC1 controller collecting dust.
I then tinkered with iRule and I really liked that I could do all my own programming, and that if I ever changed gear I was ready to go and make control updates without waiting for a programmer. However I found that some of my devices, DTV, Oppo, Marantz, would drop their "gateway" connections. The learning curve for me was longer than I would have liked so I grew impatient.
Separately I had acquired some Control4 lighting products last year and I got connected with a C4 dealer that was willing to work with me to get might lighting working even though it was 2nd hand gear. He was real responsive and helpful and so when I mentioned my frustrations with Bitwise and iRule he convinced me to try C4 for my media room.
My favorite thing is that you can get the SR-250 remotes give me the tactile feel of a remote with buttons while the full suite of access via IOS. I know many people aren't fans of Control4 but I've been happy with it. I still have some refinements I want to make to the way my system works but for now I'm happy.
