I was about to pickup a new Toshiba DST3000 top set at my local big box store but stopped when I was told the model was about to be replaced with a new one. Does anybody have information on the change? I would appreciate any comments regarding why I should or should not buy the DST3000 now. I intent on using it for all signal types (UHF/VHF/local HD TV in the Detroit area, Directv and HDDirectv). The set I am using is the Toshiba 42H81. Many thanks.
