I use a very tiny Pentax Optio S6. Around $440 - $450 from most places such as JB HiFi etc. It's a great camera for flying because it's so small and the quality of the photos is excellent. You can carry it on your belt in a small case and not even know it's there. I use it when I see strange occurences and people doing stupid things, etc. Recently snapped a guy on his motorbike on the Hwy next to me in video mode. It does 640*480 video which is twice the size of most digitals. Lets just say that with the clarity of that video, he won't be doing that for a while after I passed it onto the appropriate "department."
