| Bottom line | The Samsung E550 series LCD is a decent performer with excellent shadow detail and good colors but image softness hampers a hearty recommendation. | The Samsung E450 series plasma may not be perfect, but you won't find another TV that performs this well for this low a price. | The Toshiba 40E220U is a value-for-money television offering decent contrast and bright, vivid colors. | The Panasonic TC-PS60 plasma TV's low price, high-end picture quality, and bare-bones Smarts make it one of the best values we've ever seen. | Despite being unable to fulfill the expectations raised by its specification sheet, the Vizio E-Series remains a good choice if you value its Smarts and styling. |
