How big are your surfaces? If you can find enough marble from another kitchen on the cheap, getting it cut isn't too bad. Ours cost about £350 to get redone, and I did the templating and fitting myself, which wasn't as hard as I feared, but we don't have stacks of counter space.
thinking of replacing the 2 ratty looking hard wood tops in our kitchen with stone / marble ones. anyone done this? is it going to bankrupt us?
