In addition to be on the hunt for the right "immersion blender" I am looking to replace some of my cookware pieces. I have an electric stove top with removable (for cleaning purposes) surface elements. I was thinking that copper core cookware, like All Clad, might be best for my kind of cooktop since copper apparently conducts heat so well, and particularly because, when I use a large pot, or my oval shaped Le Creuset pot, I have to shift it periodicallyl for even cooking! Any comments on this? I know this cookware is exceptionally expensive, but it's being given to me as a gift if I choose to go with it!
