Home-made yogurt for little more than the cost of a litre of milk. If using UHT/long-life milk, it doesn't even need to be pre-heated. I stir a couple of spoons of a previous batch into a tablespoon or two of dried milk (to make it thicker) then gradually stir in a litre of UHT milk from a carton. Leave for 8 hours and perfect yogurt appears at the end. It's even the right size for re-using the containers for litre shop-bought yogurt, if the included container is still in use. I've used mine weekly for a couple of years now and it still works perfectly.
