I've recently become intrigued by the new electric smokers. I have absolutely no smoking experience. I have a few questions: 1. Is electric smoking legite? Or is it simply an outdoor oven? 2. I am familiar with the MES 30 digital and the MES 40 digital/window (been looking at it -- never have seen one in action) 3. would like to consider options/brands that offer great results, with easy cleaning for the beginner. Thank you for any info.
