I am thinking about getting a yogurt maker so I can make my own. Is it good? worth it? any recommendations on what kind of maker? I tend to be a low or no fat vanilla yogurt kind of person but would like to branch out a little if I am making my own. I read the labels of the zillions of yogurts out there that claim to do so many things, but kind of worry when I can't pronounce half of the ingredients. Thanks for any advice!
