I have looked at Vizio, LG, and Samsung. Here are three:
Lg 42LB6300 $499
Samsung UN40H6203AFXZA $549
VIZIO E420i-B0 42" $400
My main requirements are 120Hz, 40-42 inches, and can handle gaming. I would prefer to pay 500 or less but if it is worth it to get the Samsung then I may be willing to go higher. If any of you have any other suggestions I would be happy to hear them.
