Don't know where you can get them in the UK, but I recently replaced an old 15" CRT that had given up trying with an Acer AL 1751As 17" flatscreen. Many LCD monitors I've looked at aren't too good at displaying warm colours, they all seem flat and bright to me, but this one stood out from the rest for contrast and colour. And the price was pretty reasonable too. Just a personal opinion of course.
