Has anyone bought and tested the allied-kenco thermostat. I like how you can just plug it in with no wiring involved. Any temp fluctuations? How accurate are they? I'm electrically ignorant so while the PID method looks like the way to go, I think it's out of my skill range. FWIW I found a dandy commercial stainless steel fridge that I'm planning on making into a smoker. I'm just trying to get my ducks in a row before I start the project. Thanks for any advice or suggestions.
