In Memphis you can get Nature-Glo, which the Whiz has ranked fairly well. I used it for a few years and really liked it. Lights quick and doesnt put off too much smoke. You can go to the Charcoal Store on Florida st and see Pert and he will hook you up. A 40lb bad ran about $22.
BBQ shop on Madison is my favorite. Cozy corner is shaved vs pulled, they have a great hot sauce. There are also some great places that are off the beaten path but also aren't the safest. Interstate BBQ on south third st and Paynes BBQ can't recall the street name. Toms on Getwell has a great pulled pork sandwich and nanner pudding.
