I have owned Calphalon hard-anodized pans in the past and recently replaced them with All-Clad d5 stainless (which I love to death). I had the lower-to-midrange set from Target that I thought was called Simply Calphalon, but it may have been the Kitchen Essentials line. Anyway, it was terrible in every way possible. Even the handles on the smaller pans (like the 8" frying pan) were too heavy for the pan so it tipped if it was empty. Ugh, I'm so happy to have my All-Clad pans now!
Are you wanting a nonstick set or a stainless set? I'm not really a fan of nonstick cookware anymore due to the related health concerns, but for an affordable stainless set that is similar to All-Clad, the
Cuisinart Multi-Clad Pro is rated VERY highly. If I needed a more budget friendly set, I would have chosen this set. Also, the
Tramontina Tri-Ply set is also rated highly.
For nonstick, I would probably choose the Calphalon Unison set if you really want Calphalon. I have a family member that owns an Anolon set, and another family member that owns a Circulon set and they both like their cookware...however, neither of them cooks as much as I do so I wouldn't say their sets get a lot of heavy duty use like my cookware.
If I were giving a gift, I would definitely choose one of the stainless sets, BUT not everyone is familiar with cooking on stainless. I had to learn but it was very easy and now I love it. I also like that I can use metal utensils if I want. I was tired of babying my nonstick set (that still got scratches and a chipped finish even with handwashing and only using plastic utensils). I now only have two nonstick pieces: A flat square griddle pan, and a frying pan for eggs which needs to be replaced with a Swiss Diamond pan.
I also saw that Calphalon just came out with a nonstick ceramic set...I'm not familiar with it at all, but you may want to check it out.
