I'm looking at also doing a DIY sous vide with a crock pot and a temperature controller. Maybe I can set them up so that I can use one controller on both. If I get one that's programmable I can just swap the thermocouple and power leads between the two and set it wherever I need. I don't want to spend a bunch of money on the smoker alone. If I were putting several hundred dollars into it I might as well just buy a quality pellet smoker and junk the cheapo cabinet I have now. but if I were able to use the parts in more than one system it would help justify the expense of the superior system.
