I know John :) I did a lot of research into the different material types when I was having my kitchen done, which is how I got to know this guy (I went for granite in the end). Most of the stuff is black-ish but I have seen a lot of white/off-white/light-grey too (its popular in London and the south-east) as well as red, dark green, metallic silver and gold finishes (apparently quite popular in certain ethnic communities - I think thats Staron or Hi-Macs rather than Corian tho, same sort of stuff). It comes in various sheet sizes and thicknesses up to 3600 x 800 x 13 and 6mm but you can get 3mm and thicker to special order. They cut and supply for a lot of other companies in the south-east.
