I love my samsung. It's a UN55D6900 and I'm extremely happy with everything about it. I had a lot of issues looking for a TV too though, there are so many things you have to be careful about now.
The best site I found for in depth technical reviews was
Television Info and the best site for user reviews I found was
AVS Forum. I recommend shopping around a bit, picking out TV's that meet your budget and look great in the store. Then use the two resources above to get some more detailed information about them.
I found it hard looking for a new TV because salesmen will push you towards TV's where they get the best margin (if you shop where they make commission) and people that own TV's will be biased towards their purchase. But in the end was happy that I took my time.
