I would advise you to take look at Amtico range of vinyl flooring as an alternative to ceramic/stone tiles. I've just had it fitted and it's excellent. When I first heard about it I wasn't convinced. I just had a image of old fashion lino in my head, but it's nothing like that at all.
I went for the cheaper spacia range wood 'traditional oak' which comes in 'planks', but the tiles are lovely too. Basically they take really high res images of real flooring and recreate it. The range of tones and grain across my floor is very realistic. It's warmer under foot than tiles, has a 15yr guarantee, costs considerably less than the figure you mentioned and wont crack when you drop something on it. I will definately be using the stone effect tiles when I do my bathroom.
If you're in Northwest I can also recommend a superb supplier/fitter.
Might turn out not to be your cup of tea, but have a look, and get some free samples ordered from the web. There is also Karndean which is pretty much the same
