I have the LG 40UF770V, a 40" UHD, LED backlit IPS TV. I bought it to primarily use as a giant UHD monitor and it's OK at that but it really is much better as a TV. It upscales 1080p very nicely and the adaptive LED backlight makes for nice colours and contrast. Sound from the internal speakers isn't supposed to be great but I've never used them as I feed the sound through an amp and bookshelf speakers.
I paid ?400 for it, not sure about your local prices but I personally think it's very good value for money.
A word of warning though regarding audio on this and most other UHD TVs, there is a fair amount of input lag. If you have audio fed from a Blu-Ray player, for example, to the TV and to a surround sound receiver you will find that the audio is ahead of the picture. You need to feed everything in to the TV and then back out to the amp.
