I am looking to replace a 60" GW III and I an torn between getting the 55hx800 (LED 3D) or 60EX700 (LED). I have seen both in the store and like them both. My concerns are, the 3d is cool, but is it just a passing fad? And am I really losing that much by downsizing to a 55" from the 60" I have now? Will I miss the 60"? I know the different specs of the 2, the 120hz vs 240hz etc. I just want to see if anyone has any advice to give. Thanks.
