This may be of interest to some people. I recently broke my old TV and was looking for a new 50"-55" 120hz TV with built-in (not cast) smart features. I couldn't find anything close to my old TV for under $1,200 until I stumbled on this.
Note that this is the 2016 model, but many people actually prefer these over the new MU8000/MU8500. I am not sure you can get a better TV for this price.
I don't know this seller but I am just banking on their reviews being good. They seem to have a good record on shipping TVs. No tax for me in CA was also a big deal.
