Le Creuset is french enameled cast iron is great stuff. I am slowly switching all my stainless cookware to it. several companies make it now but it's not cheap.
Bad advice, IMHO. You risking cracking it if it's not heated very slowly and evenly.If you find an old rusty skillet put in a good fire until it is red hot and let it cool slowly. It will be like new and ready for seasoning.
