What are the most needed 4 or 5 accessories that I need to buy when I buy my large BGE? I now I'm getting the nest and the mate. What are 3 or 4 more that you think I will really need? I hear that the elctric starter is a must have but there are so many other accessories to chooses from. I plan on cooking/smoking mostly chicken breasts, hamburgers and once I feel confident I will be doing a 10-12 hour smoked beef brisket or two, if you think that is possible on a BGE. Thanks!
