I'm interested in the D7 line, solely as it relates to the Control Freak. I have some Caphalon, Cuisinart, All-Clad Copper Core, a Staub ceramic coated dutch oven, and a cast iron skillet. When D7 first came out, I was salivating over it. Sort of like the Control °Freak. I was waiting to see if they came out with a larger selection. They started to...but then they discontinued it! What the heck!! Do you like your D7? Overpriced? I've read that D5 is just as good and not as heavy? I can still get a set on Amazon for $799. Should I just stick with my hodge podge collection to use with the Control Freak? If D7 had ever expanded into a full set...I'd be all over it!
