Why do you need non stick pans? Ive never had a non stick pan and have had the same set for 25 years, plus a couple of Wagners cast iron frying pans. If you buy good quality normal pans you shouldn't have a 'sticky' problem! Most TV chefs never use non stick, the secret, especially with frying, is to make sure the pan is quite hot before you add a good quality oil, then wait for that to heat, then place your chicken, beef or whatever in the pan, a good medium/high heat will be fine and things shouldn't stick. As for boiling veg etc, i'd recommend getting a steamer, much healthier and more flavour and no chance of sticking!
