I'm ready to get a new Electric Smoker. I have NEVER smoked before. I am completely NEW. I have only enjoyed smoked meats and now i know I want to do this at home. The Masterbuilt Electric Smoker brand has come across my radar in the last two years but it appears that there are several [ models ]and [ generations] that confuse the field for this NEWBIE buyer. - Which model - Which generation - Which options/features are important to consider - Which price range should I be looking at? - Where should I be buying one at (qvc, ebay, lowes, sams club, home depot, etc). Thanks.
