colander, dishes, wok for the egg?

I am still learning how to cook on the egg but many pics I have seen include some type of colander or small dishes to cook vegetables in. Most of these seemed to be made of metal and a few were ceramic. I like the idea of using a colander to let the smoke surround the food better and juices drain off, and I like the idea of using small solid dishes for simmering something like shrimp or scallops in butter. The wife is also very interested in using a wok to stir fry some veggies.

I have been looking around on ebay and at local stores but most dishes like this go for $20 or more each plus shipping and I prefer to get something cheap while I am still learning and experimenting. I found a stainless steel colander for $3.00 on clearance at Walgreens of all places. It is actually made pretty well with a flat base and two handles but the metal is a little thin and I assume it won't spread the heat as well as cast iron. I also saw some older enamel coated metal dishes at a local flea market but most of them had chips in the enamel and some rust spots. Would a new enamel dish be better than stainless steel?

So what types of dishes are best for this type of cooking? Pics would be great if you have any to share.
