I was in similar boat to you OP. Hated the idea of spending £1k or more on a new TV. About a year ago I bought a 50" 4k Panasonic for £700. It broke (just stopped turning on) after about 4 months. Got it replaced and 8 months later exact same problem. Reliability issue aside, I was not impressed by the quality at all. Software was very laggy. Motion wasn't good and I just wasn't overly impressed. Black Friday I went out on a limb and impulse bought the LG OLED C7 for £1,500 and it is absolutely amazing. Interface is fantastic, easy to use, software is quite responsive and the 4k quality is just unreal.
