So the big feature I personally have always wanted for a sous vide setup is a coffee pot style auto on. When I wake in the morning, a lot of times I want to cook sous vide, but a hour~ for the water to come to temp+another hour or two for the food to cook is too long to wait on breakfast. I want something to be able to start heating a hour or two in advance of me waking up, that way it is ready to go but hasn't wasted electricity/wear and tear by staying on all night.
