Nice looking system.
I have the 659 remote and after nearly two years of use find it exceptional, especially for the cost. It is indeed a one button system.
My only complaint is the screen...it is bare minimum but I can easily live with it. I have mine tweaked so the main buttons control all the functions I usually use on a daily basis...record on the dvr, etc...this way I don't have to go to through the "device" then "next" until I find the right control I want...that is for tweaking which is usually not needed once your system is set up.
