I am looking for my first cast iron skillet. I don't have the time to search for one at a flea, antique, estate, garage sale, etc. I want a new one. I see that Emeril has one for about $30 at Macy's. It is made by All Clad. I also saw Walmart had 3 sizes by the camping supplies. They were all Under $20. Any suggestions? Online is fine as long as it is not expensive.
