I have one, and I love it. It bridges my large UPS and the mains power, so that if either one of those fail, then things keep running. I have it on mains in case something kicks up too high and overloads the UPS.

They really aren’t that much more expensive than a high end smart TV. I’ve been seeing them at about $10(US) per inch. So a 60 inch TV is roughly $600(US). But I guess it all depends on availability of them in your local market.

If you are looking for a “dumb” TV, check out models that are for “digital signage” like the Samsung BEC-H series. They are as dumb as you can get while still buying new.
