We went with a non smart 70". Smart just adds wifi, Netflix, Hulu, etc. I'd rather have a device that does that stuff- Apple TV, Blu ray player, Roku, etc. That technology changes too quick to have it in a tv. Easier to buy a $100-200 device than need to update a much more exspensive tv. Just my preference. That said, if the new tv had it and it didn't add cost, so be it.
Best Buy has their Black Friday deals on their website. They also show open box I box inventory, they do like moving that stuff and are sometimes open to offers.
