Yogurt maker that also heats milk

Making yogurt is simple: (1) heat milk to 180F, (2) cool to 115F, (3) add yogurt starter and (4) let sit in a warm place for a few hours. Yogurt makers only solve (4), which really doesn't require an expensive appliance. Is there any yogurt maker that will perform all 4 steps without any/minimal intervention?

Yes, I am that lazy.
