A couple of people I know (one from this list) suggested filling an insulated picnic cooler with water of the appropriate temperature. Using enough water
should maintain stability pretty well.


Thats how I did it before I got the Jobo, and to make things even better, I
modified an aquarium heater to maintain the temperature at 38�C as well.
