I have a bunch of cast iron skillets, and couple of griddles, and a few other pots. One griddle had a rough surface at first, but cooking on it built up the seasoning and it isn't rough to cook on now. Be sure to wash it carefully, don't scrub off the built on black surface.

I've seen a lot of cast iron cookware in Academy Sports and Outdoors if you have that chain up there. And I think Cabella also has it.
