A plasma is a way better value than a $750 60hz LCD HDTV even with an LED backlight. The motion characteristics of LCD panels are simply inferior to Plasma. If you watch sports there is no better way to watch it then on a plasma. $750 will surely get you a 42" 1080p Plasma or even a 50" Plasma. Just for example I've provided a link to a Panasonic S2 series 42" 1080p Plasma. Power consumption is higher on Plasma but so is the picture quality.
