Buying a TV

You're going to get a lot of different opinions on this. I'm inclined to go with 120hz plus those TV's usually have a few more features as well.

Not an issue with Plasma.

Sometimes I can see a difference and other times it makes no difference. And you're right, since the 120Hz TVs are newer models, they have some more features.
 
What do people think about 60Hz vs. 120Hz? Is it worth going up to 120Hz like the guy at American claims?

Go with plasma and you don't need to worry at all. If not, you must go at least 120 HZ imho. I didn't even know you could get 60 HZ any more in a good model.
