My big soup pots and roasters are Magnalite, and work great. They heat evenly, take less heat to cook, and are not too heavy for me to handle.
My skillets and one dutch oven are Calphalon, and I wouldn't trade them for anything. They do a great job, and are so easy to clean up.
I had a whole set of Le Creuset that I gave my step-son, (a handsome bachelor who cooks too!) because it is just too heavy for me to handle any more. Arthritis and degenerative disc disease have caused me to make a lot of changes is my cooking methods.
I've also got lots of cast iron and Revere ware stored away in the basement...too good to get rid of, someone may need it someday.
I also still use the old speckled enamel covered roasting pans (3 sizes) for turkey, dressing, and baked beans. And the old speckled kettle that used to be for canning is just right for a big batch of corn on the cob.
My favorite dutch oven is the one my parents got for a wedding present in 1946...I think it's made of cast aluminum or some alloy. It makes the BEST pot roast!
