Due to the side vents the SJG doesn't have as good of air flow as the SJS and other Weber models. It still has the ability to make some great food, but don't plan on getting high searing temps from it. A couple of years ago I was on a job for six weeks living in a Holiday Inn Express that didn't have a grill available. A buddy of mine and I lived off my SJG the entire time. It took a little doing to manage the small grill space but there is plenty of room if you don't try to get too fancy. We only had one evening meal the entire time in a resturant. All the others were done on the SJG that I brought.
Turning it into a mini WSM was the best move I ever made because it was getting pretty limited use until then. Now I use my mini WSM more than his big brother.
