Because I have limited patio space, I got a Big Green Egg, which is great because it can do everything: grill, roast, smoke, bake (bread, pizza, even cake), it does it all. That being said, if you already have a grill and you want a dedicated smoker, then BGE is probably not your best bet. Find something like a Traeger. I hear they’re awesome, but I haven’t ever used one.
