We used them here in FL about seven years ago. We covered 74 sq. ft. for just under $5000. I have no idea if that's a lot or not, but it turned out beautifully, and when I dropped something on a corner and chipped the granite about two years ago, they came out the next day and repaired it (undetectable) at no cost. It's a light color with gold, beige and black flecks through it, and in spite of our best efforts, there are absolutely no stains, cuts, or scorch marks on it. Almost forgot, the price included an extra-deep under-counter white porcelain double sink with a single-lever tap and separate spray hose. We did have to pay extra for a plumber to install the taps and spray as GT aren't licensed as plumbers (at least this branch wasn't).
I was out of town when they did it, but DDs said they worked quickly, quietly, and cleaned up after themselves. It took two days, start to finish.
When money falls from the sky and we renovate our bathrooms, I'm calling them again for new countertops.
Hope this helps.
