never thought of Cast Iron as expensive, if you're in the city like me, most stores have them on sale for like 50% off, just keep checking their online flyers. Managed to score a nice one for around $20, and have been using it almost every day, and a nice non-stick patina has built up. Also bought a non-coated carbon steel Wok from walmart for around $20. Same with cast iron, just keep using it and a nice non-stick patina will build up. Teflon will wear out, and it's a carcinogen. Cast Iron and Carbon Steel will last a life time, just apply a thin coat of oil after every use.
