Welcome Wehill! I was new not just to electric smokers, but smoking generally until last November when I bought my #2. I'm going to share my experiences and opinions. I'm sure others will weigh in, too.
I typically open the door on my smoker twice when doing a smoke... once to put the product to be smoked in and once to take it out. My friend who owns a #1 and pointed me in this direction when I told him I wanted to get a smoker made it clear that one of the biggest sins to be committed with this smoker is to open the door. Every time you open the door just tack on another 30 minutes and accept that you may have decreased the quality of whatever you're smoking.
I got the analog #2 and not the digital 2D because I also wanted to keep it simple and because I wasn't sure it was worth the cost. Today I have absolutely no trouble saying this was the perfect choice for me. I set the temperature and know that magic will just happen. I don't worry that it'll shut off unexpectedly in the middle of the night while I sleep. (I throw butts and packers in when I go to bed.) I don't worry that the temperature will be wonky for some reason. It just works. You didn't ask, but this brings up the second big sin... set the temperature and just trust it - don't try to use a probe to measure the box temp. You'll stress yourself out for no good reason at all. There are temperature swings, but over the course of the entire smoke it all works out and simply doesn't need to be micro-managed or even measured.
So... where do the posts come from where people are putting in more effort? Some people like to be more hands on and/or like to experiment. I personally don't think this is probably the correct smoker for them... the SI is a set it and forget it smoker. When I talk to friends and they say they want to get into smoking I always ask them if they want to get into smoking because of the art and process or because they want a super-easy, no-frills way of producing their own smoked foods. If they say its the process then I tell them to move on. If they want what is frequently called Lazy-Q here on the forums, then the SI is perfect.
I've only been smoking for 3 months as suggested at the start of this post. I've done Turkey, Boston Butts, Packers, nuts, ribs, pork loin, salmon, cod, and chicken wings. It all comes out beautifully and with no effort at all on the smoker side. My largest effort comes in prep... thawing, brining, trimming, rubbing, etc. The smoking part is as easy as my kitchen oven. If I can have this success with so little experience, someone who has been around the block a few times shouldn't have any trouble at all.
