Homegoods, Marshalls, TJMaxx; all the same company, really. They have a lot of discontinued items at very good prices. Your stuff won't match, but unless you like to hang your cookware as decor when you are not using it, that shouldn't really be important. Personally, one of the features that I find important is hollow steel handles; they stay cool enough to handle easily, but are still very durable. (Solid steel handles, while the most durable, tend to get blazing hot, hot enough to burn through a potholder at times.) Tuesday Morning also often has good deals on discontinued and/or overstock pieces.
Anodized aluminum is what I prefer for most uses, but in stock pots I prefer heavy stainless for anything water-based. For true frying (not sauteeing), or for making gumbo, nothing beats well-seasoned cast iron. For stir-frying I have a traditional carbon-steel wok that is also well-seasoned.
