Small aubrin unit with 1000 K probe. Works great for the Lee pot and doesn't take up much room on the bench. Neither HS or SSR(only a 15 amp unit) get warm at all, HS grease on the SSR and the HS. Sorry for the bad focus, but you can see how I put it together. Yea, I have to put strain relief and put the back plate on, get rid of the tape holding it together, sometime.
