If I was you id wait until they release the new series of TV, likely to see price drops on the current models or improvement on the new range. Its not as if your TV is bad at all.
Thanks, I've found the 55" e6 for £2048 and could probably get a price match at richer sounds, also it comes with free sky Q at the moment. Is the price really likely to drop any further once the 2017 models are out? The e7 version won't have 3D and I'm expecting it to cost around £3000 so I don't think I'll be buying one of those
