Hello! I'm very new to all of this. I just purchased a Masterbuilt 30" 20070910 after quite a bit of research over the past week. Delivery should be next week. I've read several reviews on this model and am just a little bit concerned about the negative ones where the unit just dies after a year or so. I ended up not paying too much for it as I had some Home Depot gift cards so I felt the risk would be worth it. Any advice is welcome.
