Check out ManCaveMeals on youtube. JM is a brethern and he has done numerous reviews of the Chargrill Akorn Steel Kamado and has recently done several reviews on the Kamado Joe and Big Joe.
He hangs around in Chat later in the evenings (about 10pm-midnight eastern time) and he is always more than willing to answer questions. He is a great source of information about both of the kamado's you are considering.
