The good news is that a good wok is very inexpensive. What you want to look for is a carob steel wok. You will have to treat it like cast iron. It needs to be seasoned and be careful of water. You can get it wet, but make sure to dry it completely so it does not rust. There are round bottom and flat bottom woks. If you will be using it on a standard range then a flat bottom will be your best bet. Some have one handle, others have two (the second is know as a helper handle I think). Some come with lids and racks and all sorts of stuff. I would not worry too much about the extra stuff though. A good wok should not be more than $30, but probably even less (maybe as low as $15). Check out Chinatown if you are close to one, otherwise look on the web. Lots of great deals.
