Hi Abwman, welcome!
Smokester is spot-on, as usual. The ONLY thing you will miss is the pink smoke ring that you get with a charcoal or stick-burner smoker. I suggest you spend some time over in the Recipes section, and look at the many pictures of incredible bark. I have never failed to get great bark - and agree with you on its importance!
You will always have the "traditionalists" who snub electric smokers, mostly out of ignorance (and I don't mean that in a derogatory way, just lack of knowledge). We have many, many "converts" from traditional smokers here, and no negatives!
Here's the advantage, at least for me: Stellar "Lazy Q!" Like you said, tending a smoker for 6-12 hours isn't a lot of fun for most; we just want the end results! With these smokers, you can actually focus on the food preparation, not the method! I think the smoke flavor is more "pure" due to a lack of influence by the heat-generating substance (wood or charcoal, or both). The units are very tight, so they hold temp and moisture very well. Most of us use a "no peeky" method of smoking; put the cold meat in a cold smoker, with a remote thermometer, and keep the door closed until it hits internal temp - it's THAT easy!
I've smoked with traditional methods, and I have people tell me my Q is the best they've ever had. No one cares how it's smoked - they care about how it TASTES! In a blind taste test, I'd put what I can make in an SI up against anyone's Q! Plus, I can make it year 'round!
Let us know how we can help, and throw the questions at us!
