Toshiba 51" HDTV Is this a decent TV? It supports all HD modes except 1080p which is understandable. Does anyone have any experience with Toshiba RP televisions? I only ask becuase Sears is selling them for $899 on black Friday (the day after Thanksgiving for the non-Americans). Seems like an awesome way to get started with HD goodness. What do you guys/gals think?
