@Rat I have a couple of these in the rooms
I know they are only 24 inch but find its big enough for a room. They also have a sat and cable tuner but the sat is not freesat set up but you can dump the channel map to usb and redo your own bouquets with a bit of jigery pokery The smart features are good as well.

They do a 29 I think for 199 as well probably same features . They have some nice network features as well ie media centre .I stream movies from the nas server to them. The wi fi is top notch too
