I'd recommend Gastrolux
Most people don't ever half of the items that come with sets. Depending on how you cook, I would go with a good saute pan, a frying pan, sauce pan and larger roaster. I recommend Gastrolux from personal experience. We have had this for many years, and love it. We started by purchasing the two handled saute pan with a lid, and used it for everything for almost two years. After that, we threw out the rest, and bought a frying pan and larger roasting casserole. It is amazing, holds the heat well, and with the chemical free non stick surface, is a breeze to clean up.
We have tried all the others, and if you try this, I know you will be happy.
