Consumer Reports likes it:
"Panasonic continues its winning ways with this 58-inch plasma. With rich, accurate colors and crisp detail, images jump off the screen, though you might notice some graininess in dark scenes viewed up close. The Panasonic would work well as the centerpiece of a quality home theater."
They also like the Samsung PN58A550 and the Pioneer PDP-6020FD (a 60").
