Resurrecting this thread for all things cookware. I am looking to replace a Japanese round bottom wok I bought here in LA that was never quite seasoned correctly and has now gained a unremovable thin layer of carbon "stuff" along one side and doesn't have much nonstick capability remaining.

I would like to start over with a new wok which I can pick up in a couple months when I'm back to Tokyo - not too expensive, maybe around 18" or so across the top, round bottom, Japanese style and high quality carbon steel - ideally pre-seasoned and ready to go.

Any suggestions on retailers with something that might fit the bill, or is it better to just wander around the kitchenware area of Asakusa and get something random?
