Cooking in cast iron/Carbon steel woks is very good for health and you can use them for a lifetime but maintenance is a big issue. They need to be seasoned every time after the wash. Also, they are not dishwasher safe. Carbon steel is expensive compared to cast iron. I like 'Mineral B' carbon steel pans. You can check them on amazon. I have a Lodge cast iron skillet and it works well.

Enameled cast iron- I haven't tried it yet. The enamel coating on the iron pan is completely safe and much easier to maintain than Cast iron or carbon steel woks. Le creuset is a very good brand and very expensive. I want to buy Stuab wok and waiting for a good deal. Here is the amazon link: https://www.amazon.com/Staub-1312906-Perfect-4-5-quart-Cherry/dp/B00IWYWHK2/ref=sr_1_2?keywords=staub&qid=1566845320&s=gateway&sr=8-2

Aluminium wok - A durable one like the above pans and relatively very cheap. I bought a 4qt one at a local Indian store for $30.

Hard anodized non stick woks - I swear by Calphalon and Circulon brands. I'm rarely using nonstick these days.

You can find all these brands on amazon. See the company's website and retailers like Kohls, Macy's for good deals. Sorry for giving you a lot of options :).

Also, if you want to use oil for high heat cooking, go for cold pressed or expeller pressed refined oils. I started using 'Chosen foods refined expeller pressed Avocado oil ' lately for high heat cooking and I love it. The taste is almost neutral unlike peanut/coconut oils.
