 I think OP is a great system. I am putting a triple screen in our Envoy, and
 I have several friends with doubles in their 4P's. As much as I like their
 system, their customer support after the sale (at least in my situation) has
 been poor. I doubt it is deliberate, as most companies tend to focus on new
 customers - though that is short sighted. Nonetheless, the system has been
 improved over the last year, and is well thought out and upgradeable (I will
 be adding FLIR to mine).
