I worked for Willliams Sonoma for several years, and am an admitted cookware junkie.
The first thing you need to know is regardless of whatever "they" tell you, there is no such thing as safe Teflon. Get rid of it all!
The next thing that is vital to understand is that good quality cookware has some heft - it's heavy. It needs to be to cook evenly and efficiently.
If non-stick saute pans and skillets are important to you, the very best alternatives to teflon are pre-seasoned cast iron and enamel covered cast iron, like Le Creuset. In fact, cast iron is one of the best ways to get iron into your families diet. No kidding! Cared for properly and cooked in properly (ALWAYS heat the pan before adding your oil and then food) it will be just as stick resistant as your Teflon coated pans. While you don't get the benefit of iron in your food with enamel covered cast iron, it is also magnificently stick resistant.
So.
I highly recommend:
Le Creuset, French made enamel covered cast iron. Beautiful and unbelievably durable, it will last for generations. I have several of my mother's pieces. It has a lifetime guarantee. If it ever chips, they will replace the piece!
All Clad, commercial weight stainless steel sandwich design. It has 8 layers of stainless steel, copper and other alloys that make for a very even, reliable cooking surface. If you're not familiar with cooking in stainless steel, it may take a little while for you to figure out how to keep your food from sticking -- always heat the pan before putting anything into it -- but it can be done.
Calphalon, absolutely beautifully made anodized aluminum. Each pan is spun, like a clay pot, into shape and then dipped in a chemical bath that creates a hard crust that will not chip or scratch off (it also turns the pans black). There has been some press about aluminum being connected with alzhimers. You need to know that it is NOT coming from aluminum pans - you breathe in more aluminum every day from our polluted air than you would ever get from a lifetime of using aluminum pans. Besides, anodized aluminum does NOT come off. The crust it creates is many times harder than the virgin metal itself. And since aluminum is second only to solid copper in heat conduction, you get amazing searing, etc., so be careful. Like the others, properly cared for (scrubbed spotlessly clean) and heated, it is nicely stick resistant.
Having said all that, here's what I use.
I own an entire set of French copper pots, pans and skillets. They've been in storage for about 5 years. I have two cast iron skillets, a 10" and a 6" I use every day. I have a few Italian stainless steel pots I bought in my early 20's, several large stock pots, a 12 "Calphalon saute pan, a very large Le Creuset cassolet pot and a pasta cooker/steamer from Williams Sonoma. Everything gets used regularly.
My point is, buy only the pieces you're really going to use. Sets of pot and pans are certainly enticing -- but if you're never going to use a 12" saute pan, why pay for it? Look very carefully at how you cook and what you reach for regularly.
Good luck!
