Samsung's UND6400 occupies an upper-middle-class station in the company's extensive LED-based LCD lineup for 2011. It's the least expensive model to deliver 3D, gets the full Smart TV suite of Internet options--aside from the browser and QWERTY remote--and flaunts a fetchingly thin bezel and minimal design aesthetic second only to its significantly more expensive linemates such as the UND7000. Meanwhile if you don't mind a thicker bezel, want to boycott 3D and save $100 in the process, the UND6300 series is one alternative.
The D6400, for its part, is still pretty expensive, but it justifies its high sticker price with solid picture quality, beating out most edge-lit LED models including the equivalent Samsung from last year. It certainly has its flaws, but all told it occupies a sweet spot for LED and Internet TV shoppers who don't want to take out a second mortgage to pay for a flagship model.
