A bit late on this, but, Currys Megastore in Wednesbury, had a big opening weekend this weekend and today (Monday 3rd October) is the last day. Bought myself the LG 43UH620V 4K TV yesterday for £349, think the cheapest elsewhere is Currys normal price of £449, think RRP is around £600. Anyway, set it up last night and the picture is stunning, can't believe you can get a picture that good for that little amount of money.
It has WebOS 3.0 and 3 HDMI, so that's a bonus as well. Personally, I think it's a real bargain, so if there are any local people to this Currys I would probably take a punt on it, they had quite a few left yesterday when I bought mine, think they were selling 250 in total.
Might be a bit late on this, but, I guess it's worth a try while the sale is still on.
