Hi Everyone, I have been debating what smoker to get and I am starting to lean towards the Masterbuilt 40. I see Sam's Club has this one for basically 300. Good price. http://www.samsclub.com/sams/shop/product.jsp?productId=prod1180971#BVRRWidgetID However, I see it is a different model number than a similar looking one through Amazon. Does anyone know if there is a difference? Two other quick questions, if you don't mind. One, do you think the 40 dollar Sam's warranty is worth it? Two, if the electric heating element goes out, how hard is it to get a replacement? I just fear spending 300 to 400 on a smoker and then in a year I just have a fancy box. Thanks in advance!
