Here is what I've had for the past year and I'm very happy with it. For 40$ you can get the side fire box and turn it into a smoker which is what I use it for when I'm not grilling. There is plenty of info online about making mods for it to reach its full potential as a smoker. Either way it's very sturdy and it's handled the elements well over the past year. Home Depot and Lowes sells them too.
