Indeed, you mostly find Sceptre at Walmart, where this model currently has a whopping 2,300 user reviews -- and four-star rating (out of five). It's not a smart TV -- you'll have to BYO Fire TV or Roku, which you hopefully scooped up cheap on Black Friday -- but it does have four HDMI inputs, so you connect all the things: game console, streaming stick/box, maybe even one of those cable-box things.
My advice: Consider adding the 3-year extended warranty for $24 or the 4-year for $32. You're still saving big on a big TV, but with assurance that it'll last you at least three years. (Speaking from personal experience and anecdotally, it seems like a lot of TV failures happen between years 2-3.)
