My Small Brinkman heating elemant quit so im using it as an excuse to upgrade. Ive narrowed it down to the Cajun or the Masterbuilt. They look like the same for the most part except the Cajun has the chute on the outside to load the chips as to the masterbuilt you have to open the door to load the chips. Im leaning toward the Cajun right now. Just wondering how long the chips will smoke for before having to load the box up again. Any tips and insight will be appreciated !
