I have decided to buy a new smoker since my Pit Boss Pro went down. I have narrowed it down to the Smokin' It 3 and the 3D. I am concerned about how long the digital controls will last compared to the Analog Control system. I do like the fact that the 3D will go up to 325 degrees, and keeps the temp inside with in 3 degrees. Wondering if anyone on here can speak to the durability of the Smokin' It 3D Model. Thanks
