Amazon offers the Samsung 51" 600Hz 1080p Widescreen Plasma HD Television, model no. PN51D530, for $649.99 with free shipping. (Best Buy charges the same, although sales tax is added in far more locations.) That's tied with several stores' Black Friday doorbusters and the lowest total price we could find by $40. Features include a native resolution of 1920x1080 (1080p), 600Hz subfield motion, 0.001ms response time, USB, two HDMI inputs, and VGA and other video inputs.
