Value Comparison Summary


The Sony KDL-46Z5100 is a significantly better HDTV than the Toshiba Regza 40XV645U in a variety of ways. It produces much more accurate colors, motion performance is better and it has more connectivity options, including access to online content. It's also a larger HDTV at 46-inches versus the 40XV645U's 40-inches. That would seem to indicate that it's by far the better value, but when you look at the price you have to ask yourself how much all those extra features are worth. At $2,200 the Sony KDL-46Z5100 is going to cost you about 2.5 times the Toshiba Regza 40XV645U. Although we're not enamored of the 40XV645U, you will have to ask yourself if the Sony's improved performance is worth that much more.
