You gotta be careful because most plasmas advertise 600Hz real big on the box, thinking that most people will see it and think it's better than 120Hz (or 240Hz) but it isn't the refresh rate. Unless you spend some cash, most plasmas still have a 60Hz refresh rate and most LCDs with a 120Hz refresh will appear much smoother when watching Blu Ray (or other HD content).
