Had a Ducane for 10 years now. Still looks and cooks awesome. I think they are called DCS or something like that. Flat cooking surface, no hot spots. The key is finding a grill with a lip around the perimeter of the burners. Trash the angled grease deflectors, buy a stainless grate, place the pyramid stones on the SS grate evenly. Had a cheap fiesta brand in college that was the same set up and it cooked great also.
I would recommend buying a green egg or some sort of ceramic style. They last forever, so you come out ahead of the game in a few short years.
