I am a great fan of cast iron cookware - and how for most cookware the material really is one of the most important things.
Cast iron: for, really good and even heat distribution, and you can get the whole pan sizzlingly hot ready for the mixture without worrying about anything melting or burning. The pan will stay flat, and the surface is virtually non-stick. It should last a lifetime.
Against: cast iron is heavy and holds a lot of heat, I think this pan weighs a couple of Kg or more. Anyone with wrist problems should consider if they can physically handle this pan. Also, because of all the good points above it will take several minutes on the gas to get this pan up to temperature - and then it will stay hot for long after that.
Overall - great for me.
