We're kicking around the idea of building in a natural gas grill , maybe a small sink and a small fridge.

First of all, does anybody have a NG grill and how are they compared to a propane ones? The idea of not running out of gas right in the middle is really appealing. Are the "built in ones" of standard sizes, so if I get cheap one now, I can yet have learned another lesson later without getting lessoned in carpentry & masonry again too? Not sure what it will be sitting on yet, but leaning toward flagstone.

What to make the cabinet structure from, wood or block? It will be covered in rock or brick veneer with either tile and or stainless top.

How about features you would recommend. I'm kind of shootin from the hip on this, as I haven't seen but a couple of these, so any input and pictures would be more than welcomed.
