A PID is most probably overkill for a smoker, a regular on/off temp controller, which can be bought for $50, would work perfectly fine. You don't need perfect control in a smoker, maintaining temp withing +-15 deg. will work, and a temp controller would do that.
Not only that, a PID may not be able to control any better than a standard controller could because of the setup and how long it takes for the probe to pick up a temperature change.
My point is, if that is the only change in the new smokers, i'd buy an old model on clearance, and add a $50 controller, and a $10 temp probe.
Let me know if you wnat information on where to buy one.
thanks for your feedback. i am leaning towards buying an old one...if for nothing else than i like to tinker, and besides, what is wrong with a little overkill - especially with cold smoking....the bradley forums seem to think a pid gives much better control...on a lighter note and back on subject...i'm off to butcher-packer (the store not the website) on saturday...one of the good things about living in detroit. getting some pink salt and making a corned beef.
