I have a Samsung 46" 8000 series 2012 model. Best Samsung TV I have had. I paid $700 shipped back in 2012. Model is below. I dont think this model is available unless used but this particular model is better than newer models nowadays.

Few months ago I was planning to buy one but I hold off. But the model I was gonna buy was the Samsung UN65KS8000 65-Inch 4K Ultra HD Smart LED TV (2016 Model) This is even better than 2017 according to TV experts reviews.
If you care about best TV ever made in the last 15 yrs, its the Pioneer Plasma Elite made in Japan. I still have it and working like a charm. These are not longer in production. Cheers!
