You should check out those reviews yourself. Sometimes the complaint is something that is not important to you. But I also would caution spending good money on something with bad reviews.
I too use "odds and ends" cookware. My favorite pieces are from Marshall's (TJ Maxx). I have a Wolfgang Puck large chicken fryer with lid that goes in the oven. It is stainless and is Not nonstick but cleans up better than nonstick. My two skillets are Kitchen Aid ceramic non stick in medium and small size. (They were $10 each) I also have a big stock pot from Marshalls because I make lots of soup.
