Every so often...
Looking at this, and a few other threads as well, it seems as if, every so often, someone chimes in as the "voice of reason." The time has come again.
It's very easy to overrate the distinctions between various brands of cookware as well as the importance of materials and construction. From a practical standpoint you don't need Le Creuset, you don't need Mauviel, you don't need All Clad. What sets these and similar brands apart from the herd is not performance but appearance. Indeed from most performance perspectives these are poor values. In addition, most of these high-end name pots and pans are much heavier than they need to be. Most of the reason you don't see these types of pots and pans in restaurant kitchens is not their expense (at least not taken alone), but the lack of rationale to spend the money.
In some ways the high quality of the high-end lines hurts them. They are heavy. Weight is more important with pans you'll use for sauteing and/or browning than pots. You want something light enough to lift so you can toss, shake and slide the food by hand. Thats partly why plain ol' mid-weight, cheap, commercial aluminum and carbon steel pans one sees in most restaurant kitchens are superior -- not just cheaper.
When it comes to pots -- all the high-tech even heat distribution stuff doesn't matter much. And again, mid-weight aluminum does as good a job as anything else. Of course, you want to avoid long exposure to high-acid foods to prevent discoloring the product. So it's nice to have at least a few decent, stainless pieces.
Cast iron is another thing altogether. Holds the heat like nobody's business. Nice for fried chicken, corn-bread, and whatever else you cook by overloading a hot skillet. Otherwise, it's just heavy. Enamel over cast iron loses the heat retention value of ridiculous mass and exchanges it for an absolute superiority as braising material. But c'mon! Braising is really no big deal, you don't need golden vessels. Besides, the stuff is expensive and fragile. Also, there are less expensive approaches than Le Creuset.
None of the above is to say you shouldn't buy and love what you like. It's beautiful, no doubt about it. And it works well, if you can deal with the expense, weight and maintenance. But you don't NEED it. And when it comes to pure performance, you can do better for a lot less money.
