On my trip to Newfoundland this summer, I found the portable induction stove very handy to help with quick breakfasts outside and searing steaks in the evening after they rested in the sous-vide bath for an hour and a half to a perfect temperature of 129 degrees. It comes with a convenient canvas carrying bag and hides unobtrusively in the closet when not in use.
If you must have consistent low temps for your recipes, Christmas is right around the corner, and a Vollrath would fit nicely down the chimney. Just saying . . .
