Discontinued I believe. All 3 are 12"/30cm. Weight & construction were what impressed me. Nice & balanced. I'm thinking of grabbing one of them so I'm not going to reveal the location or brand until I have some time to think it over.
Stir Fry that looks more like a oversized saucier.

I came across this higher end AC C-Core after & twisted my wrist. Way too HEAVY. I don't know how anyone can use this pan unless they're on steroids. Also I just remember it almost slipped out of my hands onto the floor because I applied sunscreen on someone. Once again, beautifully crafted, but not "practical" for everyday use.
All-clad would be my dream set. I'll probably buy some piece at a time, but I've been looking for stuff I can buy a few at once that will instantly replace my current cheapo set. I did get a set off an overstock sales site and they are alright, but won't last long. I went with a ceramic coated SS. The pans are light and the ceramic coat isn't great, but they'll work to replace a couple of the teflon pieces.
I have the Calphalon tri-ply and LOVE it. It's heavy enough to be sturdy, but not so heavy it's awkward to handle. Quality is really good - nicely balanced, even pans. If you follow the instructions and heat them up properly with a skim of butter or oil, they are nearly as non-stick as true non-stick. They're easy to clean too - barkeepers friend on everything but the shiny part will easily remove any/all marks your food may make on them.
If you're patient, you can find a lot of the Calphalon pans at TJ Maxx and Ross. I built my entire set without actually buying a "set". Just the other day I found a saute pan that runs $100 at BBB for $40 at TJM
It totally depends on your stove & the type of fuel it uses. Electric will require a nice thick bottom to cook food properly.
A better set will distribute the heat more evenly & you'll create more edible food instead of turning the ingredient into carbon. Less likely to warp if you need to dunk it in cold/ice water to stop the cooking process.
Cheap light cookware limits the types of cooking techniques you can use. Also will melt nicely in a oven that's heated over 400 degrees.
You don't have to spend a lot of money. $20-$40 will get you a decent pan, but choose something that enables you to utilize your style of cooking & will accommodate the amount of food you need to prepare.
Most people don't really NEED a full set of cookware.
