Many people want to take the inexpensive route and not buy a yogurt maker at all - using their oven as their heat source. There's nothing wrong with this option, but I feel it wastes a lot of heat and electricity because you have to leave the oven on for at least six to eight hours. Personally I think it would be less expensive to invest in a yogurt maker since they are more energy efficient and don't use nearly as much power as an oven. I must say again that the best yogurt maker is the least expensive option.
Some people like to use their microwave convection ovens as a heat source. These are also larger appliances that draw more electricity therefore they run up your electric bill if they are left on for hours at a time. Not to mention that you can't use the microwave while it's being used as a yogurt maker. Plus, who wants to listen to the constant noise of their microwave for hours. Yogurt makers are so much more quiet.
I believe the best yogurt maker for your money is the Cuisipro Donvier Electronic Yogurt Maker

If you are looking for something less expensive, I'd recommend the Salton YM7 42-Ounce Electric Yogurt Maker with 7 Glass Jars
