How about one of these as the focal point of your patio:
I haven't used a gasser for 4 years now, and I can't say that there is anything I miss about it. Gas grill heads for a built in setup are not cheap. If you want flexibility, then you could even buy 2 BGE's and still spend less than you would have on a gas grill.
However, I do like landarc's idea of using the gasser to park the know-it-all!
