My fiance and I live in a condo so we don't have a lot of space but we desperately need good cookware. He got wiped out in a divorce and I never had much to begin with. I'm no gourmet cook but I'm getting better and looking to start taking some cooking classes. What would you all recommend to get us started with the pots/pans basics. Does brand really matter and should we go all stainless steel or non-stick?
