Bamboo floors are fantastic, A friend of mine got one put in to his conservitory and it looks great, he has no problems with it at all.
It really makes no difference what floor you go for, as long as it is installed right. There needs to be a small gap between the wall of the room and the floor to alow for expantion, and then the gap covered with a decoritive beading. As for the colour fading or changing, he has had no problems yet. It's in about 2 years now.
