A non-stick pan needs to be heated to close to 500 deg F for the toxins to start coming out. If you put anything in the pan (oil, water, food), then the surface temperature will not get that hot as it transfers the heat to the contents. So, just make sure to put something in the pan.
As a wedding gift, my college friends got together and purchased us a very expensive multi-piece set of All-Clad that included a 12" skillet with non-stick coating. It's still in great shape now, 11 years later. Take care of it and don't abuse it and non-stick can last a long time.
