I am looking to buy a new TV Vizio from Sam's or Costco. I know I want to get the 47 inch but I am not sure to buy the 47 with 240 hz, the 47 with 120 hz, or the 47 inch LED. It is for everyday tv watching, video games and watching DVD. My kids are not going to know the difference in any of them but I do not know which is the best for the money. Thanks for any suggestions.
