One thing that I haven't seen mentioned yet is that most of the high-end makers of pots and pans (all clad, le creuset, etc.) also sell their "seconds" at significant discounts. You can get them online and at some of their outlet stores. The defects that make them seconds rarely impact their ability to cook.

My opinion on pots and pans is that you should consider non-stick pans to be disposable. Even the best ones will have their teflon worn down over time. So I don't waste money on high-end teflon pans. I buy heavy duty aluminum teflon pans from restaurant supply stores. My personal preference for non-teflon pans is enameled cast iron and/or clad stainless steel pans. These pans will last a lifetime. So people should buy ones they're comfortable spending.
