I'm sure this has been asked before - but still.... you opinions would be appreciated. Is the quality of the Reon Scaler in the 875 worth the asking price over the 805? I do actually watch quite an amount of Sky SD material! Also - this will be fed to a 50" 720p Plasma, with a resolution of 1365x768 ... would it make sense to upscale to 720p (amp doesn't do 768p right!?) and let the TV upscale a 2nd time? Or should I feed the TV 1080p and let it downscale !!! Cheers.
