I got this TV several months ago from Sam's Club (new) and so far so good. I'd give it a 8/10.
The picture is good and the sound is good (considering it is a TV and not a 5.1 system). However, it takes several seconds to turn on initially.
Also, when using the internet apps, it sometimes takes a while to think, and it has even frozen up a few times (and I had to pull the power cord out to restart it). I haven't had connection issues, but I am plugged in with ethernet instead of using wifi, since that will always produce a stronger connection (and it is mounted literally right above my router).
For the cost, it is a great deal.
