I'm considering buying a new lcd for my brightly lit living room, TV close to the window. From what I can read LED is the way to go if I can afford it. Is 240hz worth extra cost over 120hz? Is there much of a difference? The sales guy at future shop says there is not a big difference but I wanted some other advice. If budget comes down to a 120hz LED or 240hz lcd, which would you go with? Thanks.
