I have plenty of saucepans and frying pans with metal handles and don't understand at all the objection to them. The handles barely become warm to the touch in normal use, as they are joined and made in such a way that there is low thermal conductivity from the base of the pan to the handle. It's really not a problem. Meanwhile the durability and easy of maintenance of stainless steel means my pans are unlikely to deteriorate.
A casserole with metal handles is another matter however, as it's quite easy to forget you've just taken it out of the oven and grab the handle to give the contents a stir. Don't ask me how I know.....
