Newegg offers the refurbished Samsung 50" 1080p WiFi LED-Backlit LCD HD Television, model no. UN50F5500, for $559.99 with free shipping. That's $187 below the lowest total price we could find for a new model. It features a native resolution of 1920x1080 (1080p), WiFi, Smart TV with Samsung Apps (including Netflix, YouTube, Hulu Plus, and more), USB, and four HDMI inputs.
