I'm an absolute newcomer to this forum and a newcomer to "cast iron collecting" for lack of a better term. I have purchased a size 3 and 7 Griswold, am preparing to clean and season them, and now am looking for a size 10 or 11 Griswold or Wagner piece. These items will be USED daily. I have thousands of dollars worth of All Clad that I love, but the non-stick properties of these vintage cast iron skillets intrigues me. That being said, I have about $250-300 that I wish to spend on a Griswold 10 or 11. Do any of you have recommendations as to what logos I should be looking for and what I should be staying away from? I want pre-1940 as this has been stated quite frequently as the "good iron" period. I've been on Ebay and there is so much to choose from that I'm going in circles. Also, does anyone know if skillets with heat wrings will still work effectively on my induction cooktop. Any help or suggestions would be greatly appreciated.
