My experience is go with the older models, real heavy iron from the 70s or 80s, and build around them. The new stuff is paint-heavy and iron-light.
You can park a smoker and a griller, stone/granite/countertop around them, in a corner of the back yard and achieve the heat potential and esthetics your wife is looking for.
I tend to forget that issue. That can be important. Good point.
Not to me, personally, but for those that have wives.
