[size=12]Even though I have a pretty decent sized collection of Griswold, I don't personally use any of it for cooking. I know that this is an area where almost all of the people who post on this forum would disagree with me (the last time I even brought it up, someone responded by saying, "How sad," so I haven't mentioned it since,) but they're welcome to do with their own pieces what they want to. When I'm doing everyday stovetop frying, I use one of two types of cast iron: Cheap Wal-Mart Lodge or Cheaper Taiwanese skillets that were given to my father as a gift a while ago.
Why? Because then I'm not risking anything valuable. Even if I wanted to pretend to be enough of a cast iron guru to be totally above the risk of accidentally overheating and warping a skillet, I can be as butterfingered as the next primate, especially when I'm handling burning hot metal with an old hot pad. I already cracked my Wal-Mart Lodge skillet somehow -- don't ask me how or when -- and I'm not loosing any sleep over the fact. If I accidentally cracked or warped an expensive Griswold skillet (and with the high prices of late, there aren't too many cheap ones anymore) then I'm out the dough, when I could have done the same cooking job with an expendable contemporary or Asian piece of cast.
So, even though many may shun the practice, I wouldn't be afraid to use them for everyday. I'm not interested in buying yours, I wouldn't try to sell them, (unless it's for a dollar each at the local rummage sale, if you want to get them out of the house,) and if I was you I wouldn't buy any more of them. But in my experience, they're perfectly useable, and perfectly expendable. They're just not Cadillacs.[/size]
