Kitchen countertops material
My wife actually trained to be a certified Corian installer, but it turned out to be too heavy for her to move around.
(She was formerly a professional laminate and cabinet installer and finish carpenter.)
That said, I find it to be a bit too "institutional" looking for my tastes.
We currently have butcher block Formica. My wife hates it.
I love it and it has actually never gone out of style (and probably never will).
We found (and I pointed out a few times when my wife "failed to notice") that it's considered an "extra cost upgrade" now, and it's often featured "up front" in the show rooms.
