For all those that are debating between sizes I wanted to give you my opinion on SI #1 that's I've been using frequently over the last few months. Note we use smoker to feed just 2 people. So far only one occurrence when I wish I had a #2 instead. I had a rack of ribs in, which in the #1 requires you cut the ribs in half. I like to smoke with a pan under my meat so I don't have a mess to clean up. This means one rack of ribs takes up both racks in the smoker. I wanted to do a tray of smoked nuts that day as well but didn't have the room. I'm still happy with my decision and would buy the #1 again if I had a chance to do it over. I like how light it is, which allows me to lift it up onto the table on my deck, I like that it's only 350 watts so it's cheap to use, and you can't beat the price compared to the #2 and #3. I would also recommend none of the accessories. The cord hanger is fine, but it's not worth the price after it bumps the shipping $6 or so. I use a $7 air conditioner cover for it and it works very well. I think for a 2 person household the #1 is just fine. If you feed more than that or use it to entertain often, I'd definitely buy a larger unit.
I have the same problem with my number 2, but at least when I cut the rack in half, I can put both halves on a single rack.
