There are some terrific deals on larger TVs at the moment (32" and up) but if you need a smaller, high quality one prices are still high. Most 25"/26" sets are in the £300-£350 range. This includes the highly rated Panasonic TX-L26X20 at £349.99 most places.
However, Currys still have limited stock of the almost identical predecessor listed in this post at £249, or £10 less if you order on line (can reserve and collect). The only difference is a slightly different connector layout and 2xHDMI rather than 3x. Picture and sound are identical.
Don't forget Quidco for another 3% off!
This set has been highly praised in reviews. Averages over 9/10 for all aspects on Reevoo (via Currys link), including sound.
I did look at the LED backlit sets but there is a real problem with sound on these - they are so thin that they can't get decent speakers in them and you really need an external speaker set; that may be fine with your main large screen TV but is very inconvenient with a smaller, secondary one.
Before someone points out that it's not full 1080P HD, it really isn't necessary on a 26" set.
Hope it does someone else a favour.
