You can’t go wrong with a Samsung.
I got a new Samsung 55in LED 3D ‘Smart TV’ a few months ago, and it has been fantastic(never use the 3D so I can’t comment there). I also have a 52in Samsung LCD that’s a few years old, and it’s still flawless.
Huge thumbs up on Samsung and in second place, Vizio.
Have several of both with no issues ever, going on 7 years for my oldest one.
Love my 60” Plasma Samsung.
