I am getting a new HWS/SJ/J instal saturday. I will have the hopper in my living room where most TV is watched. The others will go in our main and guest bedroom. Looking at things from a standpoint of how long does it take to start fast forwarding after hitting the button or how fast does a channel change. Is There any reason to believe the SuperJoey would be of any significance better than the plain Joey. I want to wall mount the one in the main bedroom and I can not find a superjoey wall mount
