I recently bought the $18 one from Wal-Mart and I have used it a few times in the last two weeks, made spaghetti sauce and soup. Matter of fact, I have bought two. The first one I melted the bottom onto the stove because I turned the wrong burner on. Now I put the cooker on a big wooden board, not on the stove. My senior moments are much longer than moments.
