Update 8/29/31: the SL-2372 failed on me with a large crockpot with a 375w rating so I now suggest you get the PID with the mechanical relay that can handle 10 amps...

Here is a parts lists for my home brew Sous Vide
For those of you using a very large vessel with a large heating element might want to get this controller with an external SSR & heatsink. Check the wattage rating on your cooker...
http://www.auberins.com/index.php?main_page=product_info&cPath=1&products_id=3And a 25A SSR...
http://www.auberins.com/index.php?main_page=product_info&cPath=2_30&products_id=9And right now I am using a regular oven/grill thermocouple that is not water tight. This would be the temp sensor you want to get for your PID. It is a RTD that is water immersible. I plan on buying one for my controller...
http://www.auberins.com/index.php?main_page=product_info&cPath=20_15&products_id=46Now there is a selection of project boxes available to house your controller. I used a old power supply case for a computer I had laying around. Here is a link to their selection of project boxes...
http://www.auberins.com/index.php?main_page=index&cPath=7_34Now as far as wiring I took a extension cord and used the receptacle end for the cooker to plug into and wired the hot side to the SSR on the controller and neutral tied into the neutral power connection at the controller. The plug end of the extension cord supplies power to the controller. There is a wiring diagram that comes with the controller instructions that shows how to control the load directly with the internal relay. That is the diagram you will need to follow...
The load side of the receptacle will wire to number 6 and the neutral side of the receptacle will wire to number 10. This way the SSR will switch the load side to the receptacle on and off.
The load side of the plug will wire to number 9 and the neutral side will wire to number 10.
Then you will need to loop a wire from number 9 to number 7.
If you use the RTD senso the SN setting on the controller will need to be changed. The pt100 RTD setting number is 21.
The T setting on the controller will need to be set to 2
And the OUTL setting will be at 0
Then run a auto-tune and the controller will learn how your cooking device heats and responds. Then when the auto-tune is finished it will save the settings for that cooker.
If you change cooking devices just re-run an auto-tune.
Now about the cooking vessel. Well pretty much any electric slow cooker, rice cooker, electric roaster, electric fryer, etc can be used but it must not be digitally controlled. One without a thermostat is best. The one I am using just has low, high and off. And always use in the high setting.
I have read that the rice cookers provide the most even heating and are preferred. Crock pots come in second. And the cooking vessel should have a lid to keep moisture and heat in but is not required. You will need to fill up with water more often if there is not a lid available.
Let me know if you have any questions.
