Please can anybody recommend some pans that are extremely durable? My current ones have lasted about 5 years but now the non stick is starting to flake off. I need to replace saucepans and frying pans, and ideally the whole lot will be non stick. I don't mind paying £££ if they will last for a really long time - I don't want to buy cheaply and then have to replace them again in a year or two. The thing is, they need to stand some abuse as various people cook in my kitchen and I cannot be precious about only using plastic utensils and scourers. The pans need to go in the dishwasher too. My hob is gas. Thanks in advance for any recommendations!
