I was looking at a cheap universal control to control 4 - 6 items, ideally everything that I have but really if it just controlled the main things, Hitachi TV Pace digibox Arcam amplifier Toshiba DVD player could also add an Akai VCR and Marantz CD player but I am not that bothered about them to tell you the truth as they do not get as much use. I was thinking of a Kameleon 4-1 or 6-1 my only concern is do these work with remote extenders? As my digibox is sitting behind the TV and I use a one for all remote extender to control it. Stupid question I guess but just want to make sure. Thanks for any help!
