Thanks MB! I wasn't seeing much reason to spend the extra $100 on the other unit...but wondered if I was just missing something.
I usually shop Amazon to find products/reviews/etc...then I use froogle (google shopping) to find the best price...which is almost always through an amazon business partner. e.g. the 8 qt pot is available for only $50 more than the 5qt...which seems like $50 well spent.
I guess the induction unit works with this stainless PC b/c of the embedded disk in the bottom?
