I love my sidecar and they are great cheap alternatives to have 4dtv without spending much money, but I can see how one of these could prove to be a real pain for most average satellite users. Since Motorola stopped manufacturing them i can assume they had some complaints with the fumbling of two remotes and since some analog receivers sat names can't be changed, you would have different names for the same sat to further confuse people.
My setup is quite complex for most since I have a free to air receiver, dsr-905 sidecar, ORB-7500 analog receiver, Bose 5.1 surround system, US Digital over the air HDTV receiver, and a DVD recorder I have 7 remotes on the coffee table.
My friends and family are stunned by the remotes and don't even try to figure out how to use them-LOL
It's a great hobby. Trucker
