For non stick life long pans you cant beat cast iron - the Le Crueset range are VERY expensive, you can buy plain non branded cast iron pans in 'Homestore and More' on the Belgard Road - I think I paid 35ish euro for the biggest pan, they have varying sizes, types and woks in cast iron also.
Cast iron must be looked after, never wash with soap - only boiling water and always re-season with a little oil after use - they are lifelong pieces of kitchenware.
Im less fussy on pots - I tend to just use whatever the most reasonable brand at the time is and throw them out if they develop problems like the base going uneven or the handles cracking. Copper based pots will distribute heat better but the last set I had with copper bases, the copper started peeling back with usage - so be careful. I think the Jamie Olivier set looks quite good?
