I've spent close to 6 digits, had a "professional AV company" install a 16x16 Crestron matrix switcher in my house, and it's the WORST electronics purchase I've ever made.
1. The product is unstable. The device frequently freezes
2. Installation and programming took forever (I am NOT exaggerating). It took over 5 months. Imagine someone sitting in your house almost daily. Yes, it sounds ridiculous, even ludicrous, but that's exactly what happened
3. After months of pain, now my AV company is saying that I need to swap out all my Apple Airports (all 10 of them), with Cisco routers. However, Cisco routers are not as user friendly, iMacs, iPhones, iPads, and even printers are hard to connect to the network
The system might be perfectly fine, and this may be a one-off situation. Perhaps my house is too complicated (or even messed up), but as of October 2012, I feel like a guinea pig. If you're considering it, I would urge you to give it some thought.
BTW, I did use an authorized Crestron dealer, and a very reputable installer. I think the device is too new, and everyone is trying to figure this out.
