Zebra, I own a #2 and experienced the same problem with temperature that you're describing. I decided to purchase the Auber PID and rewire the thermostat so that I can exceed temperatures of 250º and have more control over my cook. For the record, I also own a Big Green Egg (BGE) and use a BBQ Guru DigiQ 2 to maintain temps when I'm cooking with that device.
The best part of the Auber is that it has six different phases, although you don't have to use them all. I like using my #2 for smoking fish, and the Auber allows me (with the use of a cold plate) to turn on the oven for 15 minutes to ignite the wood (phase 1), then turn off for 20 minutes and let the fish cold smoke (phase 2), then come on again for 12 minutes to reignite the wood (phase 3), then go off again for 30 minutes (phase 4), then come on at 225º until the fish reaches 140º internal temperature and shut off (phase 5). Without the Auber, that's all a manual process, and somewhat difficult with a
Smokin-It smoker since the thermostat varies as much as 20º each direction. With the Auber, it's a piece of cake and the temp never varies more than 5º.
I don't think this issue is unique to
Smokin-It. I think most electric smokers use a non-digital thermostat and with the exception of the very expensive smokers, top out at around 250º.
I totally get that the Auber is a $200 item and adds considerable expense to your smoker. I'm retired and on a fixed income and I thought long and hard about it before I pulled the trigger. Having owned it now for about 3 months, I'm very glad I did, and my cooks have been very successful! My smoked fish is in very high demand with my family and neighbors!
I've also done ribs in the #2 by setting the Auber to 225º for 5 hours (St. Louis cut) and they come out dead-on perfect. It's kind of a shame that the base product from
Smokin-It doesn't have a better thermostat, but I don't think temperature swings of 20-30º are necessarily detrimental to being able to create great Q. The real trick is to buy great meat and cook it low and slow. The
Smokin-It #2 will definitely do that, with or without the Auber PID.
