Some things I've learned... 1. I'm not a professional.. so I don't need a professional level smoker. 2. I started years ago with a cheap wood chip smoker that had a dial used to set the temp, but did not regulate its temperature. I spent a ridiculous amount of time trying to get the Temp right. So get one that has a digital temperature regulator. 3. I rarely have to feed groups of 20 or 30 (and one pork butt can feed plenty)... So why would I need a huge smoker that fits 10 pork butts? Get one big enough for what you need. The one l linked is what I use and it can fit more than enough to feed 20 people. 4. If I haven't said it, pellet smokers are soooo easy. Fill up the back with pellets, set your temp, put the food it.... And that's pretty much it. I can fill up the hopper on the back and it can last all summer if I smoke something once a week or so. 5. I've tasted things smoked from all different types of smokers, and, unless it's done on a cheap smoker and they don't follow directions (like use too much smoke or cook at the wrong temp/done temp) then you really can't tell a difference in taste. So don't feel like you have to get a special name brand smoker that costs a crap ton of cash for amazing flavor.
