Does anyone have any experience with granite tile countertops? I'm considering them because the tile is so much cheaper than slabs, but I imagine they will have to be applied to a specially prepared surface, and the labor for the edging would be considerable. I can't get an answer from the homestores on these components of the process, so I can't get a sense of whether the tile will really be a savings. What's your experience? Thanks in advance. I really appreciate the advice you all give. You've saved me from some BIG mistakes. -Denise
