>and many quite good quality ones from volume or badge engineered brands that techno-snobs tend to ignore.
The OP isn't going to get rid of his existing TV for on that is merely "quite good", especially if he expects it to last for five years at least (five years is becoming the warranty period people expect from TVs - see HotUKDeals.co.uk for discussions about UK TV retailers such as John Lewis and Richer Sounds).
'Techno-snobs' may ignore badge-engineered TVs, but it is hard enough to find professional reviews of low-end LG sets, let alone a Tesco special. When I have read reviews of Technica et al - in the Which? magazine - they have been slated as a false economy.
55" 1080 TVs range from £500 to £1000. Yeah, the pricier ones have 'smart features' (that many of us will find redundant), but also vastly better black levels, contrast and motion processing.
Now is not the time to buy a new TV. 1080 sets will soon benefit from quantum dot filters (nearly as good as OLED but much cheaper), and 4K sets will be a safer bet in a years time when standards and formats get smoothed out.
