Not sure what to buy for cast iron? This is a great starter - you get a skillet, saucepan, and they can be used in tandem with skillet as the lid. Size doesn't feel too small, especially when you try lifting the saucepan full of food. Helpful having the holder opposite of the handle. Make sure you buy extra hot pads or the kind that go over the handles. We have a gas stove and the temperatures rise quickly, and I would assume electric stoves would have a similar effect. 

Pros: Two-in-one, price, size
