For a grand - you could almost buy 2 26" LCD TVs.
For that money, I'd say jump in at the top - Loewe Concept. If you can push the budget to £1300, then the Xelos is available.
Loewe is considered to be the pinnacle of LCD TVs, and uses Sharp panels. It's their driving electronics that makes the main difference, and system software. Maybe that explains why Sharp bought in to the company for 30% shareholding.
Anyway, if you don't want to blow the whole grand, then there's Sharp GA6/GD7 and JVC DS6. Others would champion the causes of Panasonic or Sony.
At the end of the day, only you can decide which one you prefer on looks and quality of picture.
If you did opt for the Loewe, it's a bit like buying Apple computers - initially slightly more expensive, but hold their value better in the long term. Also, not the most common brand you'll hear talked about - so you can act aloof if the desire to do so, grabs you.
