Cast iron is awesome. Even those rusted up ones you can find at garage sales or flea markets can be re seasoned back to good as new. Although I wouldn't recommend them for glass top electric stoves though. If you have a self cleaning oven it is real easy to get the rust and etc. off just put them in the oven and run the self cleaning cycle then wash and re season them. Good as new. I love mine. The best non stick pots or pans you can get in my opinion. Only shortcoming is that acidic foods will remove your seasoning. But that is basically the only caveat I know of.
