I’ve only had experience with a smaller version by Ducane, but it sucked. Uneven, unreliable heat. (BTW, it was a friend’s grill that I often "captained", so maybe it was just a lemon.)
I was really surprised, because I had read so many good things about Ducane grills.
I trust the comments above (and I know CheeseWit is reliable), so you’ll probably do fine with that grill.
From personal research and talking to people I know, I would buy the Weber Genesis Silver B. Seems to be the best for the price.
