Sorry for the extra reply but I also thought of a brand that Ebuyer and others sell which is perhaps reasonable - Teco. They are a major Taiwanese company and I have actually seen one of their sets in the flesh and it was quite decent, the viewing angle was fine too. That said it was a larger 42 inch screen but I am sure they make smaller sizes if that is what you are after.
Just to give an idea of their prices, they do a 37 inch HD-Ready (720P) set for under £500 -
