There are many different types of grills and smokers available for sale. Electric and gas grills tend to be the easiest to use and clean up after, but don't contribute as much to the flavor of your food. Charcoal and wood burning products are a more traditional way of cooking outdoors, and are a better way to find the taste of grilled food.
