I have been trying to research the PowerFocus HD4 CRT that Toshiba uses in their RPTV's. So far I have come up empty for any information at all or even a picture. The Toshiba website is very stingy with details and gives no info at all about the CRTs. Does anyone have a source or a website that can tell me anything. I am trying to compare them against the Hitachi Guns and lens system. I am considering the Hitachi 57S700 series or the 57HX93 Toshiba series. I really need some input here as to which TV has what features, which would be a better choice and why. Toshiba has what they call TheaterNet for setting up devices to your remote. Is it any good? Please give me some input here. Toshibas are always a little cheaper for some strange reason.
