First - I know the OP went with a charcoal grill and has already ordered it.
That said, I went with a Charbroil Grill 2 Go and tried it out over the weekend for the first time. It heats up very quickly, and cools down just as nicely.
One of the factors I used in making my choice was how many 1lb bottles of propane I can buy for the difference in price between this grill and the Weber Q1200. Works out to be about 14 bottles plus a few good steaks. ;-)
