S.K.
We have 2 different types of Granite in our kitchen - a black and a lighter 'flecked' brown/cream/caramel granite. I would NOT do black again - it shows everything especially if you have hard water. The multi flecked one is great b/c it shows nothing and never looks dirty (which can actuall be pretty gross at times when you put your hand down and it lands on all sorts of crumbs you didn't know were there!).
Re: the post on having to seal Granite - it's super easy... you just do it like you do the grout in your bathrooms...it's a liquid you pick up at HD and you just spread it all over with one of those big yellow sponges from HD and wait for it to dry. Very easy - not sure what the other poster is speaking of...
I would stick w/ a basic and not do anything too trendy b/c if you ever have to sell there is nothing worse than going into a house that is dated by it's hard surfaces (i.e. the dark green granite that was so hot in the 90's, Mauve bathrooms, etc., etc.)
On a different note I just saw a Dr. OZ show where they had a Geiger (sp?) counter - the devise that measures radiation and they put it up to a bunch of different granite samples and one of them registered so high that an Oncology Dr. said he would have all of the granite removed from his house if his kitchen measured so high. Apparently a lot of granite has radiation. We're planning on moving in a few years and that alone was enough to make me not interested in putting granite in our next home. I use to hate the man made products but they have come a long way and some of them actually look like real stone now (Cambria has a great limestone looking product - great for bathrooms). Good luck!
