Buying a new tv

I want to buy a new TV as mine is getting on a bit now. Looking for about 32" (thats probably the biggest I can go as otherwise I'll have to re-arrange my room to fit it in). I don't really have a set budget.

While I will watch a few films and tv shows on it, I'll mostly use it for gaming. I've been looking at a few TV's but I'm not really sure if they're good + worth the money. Also if you have any other recommendations other than the ones I've been looking at that would be helpful.

The ones I've been looking at:

Any help would be great.
