I got my #10 Griswold and #6 Wagner from my Grandmother. I love cooking in them. They are so nonstick. Since then I have added 2 #8s a #9 griddle and a #9 waffle maker. I love the smooth cooking surface on the old CI. I picked them up at auctions. My dutch ovens for camping are the newer Lodge and you can sure see the difference.
Lodge is the only CI made on the US now.
You can usually find the older pieces at flea markets, yard sales and auctions if you have time to look.
