3D tv was the biggest waste of 2k for me ever, it rarely gets used as 3D, came with only one set of shutter glasses which are £70 per pair as there brand specific. And the 3D isn't amazing. If you use it for stuff like xbox or ps3 ect it just gets frustrating. On the plus side certain brands, like the samsung I have, come with a built in 2D to 3D converter so you can watch normal tv in 3D if you wish but it's not amazing. I'd hold off from a 3D tv for a few years until they perfect the tech to be something like the nintendo 3DS which doesn't require glasses.
All in all not worth the money at the moment, if your going to spend big on a tv go oled but LCD would be my recommendation
