I use a little Nikon Cool Pix. It takes great photos and pretty darn good video. The zoom capability is not the greatest so birds that are out there a couple hundred yards are tough to see. But all in all it is a great little camera.
Here is a video of my last hunt of 2010, it does a good job demonstrating the clarity of the camera and if you watch good you can actually see my mallard falling out of the sky. You might have to watch it a couple times as I did not have it zoomed tight but you can see the mallard fall in front of the snow background. I am almost always running the camera and hunting myself so it is difficult to zoom on anything as it is happening so I keep it set at a fairly wide angle to capture as much as possible.

you might also want to check out this video of mine just to get another look at the clarity

for less than $200 it is a pretty good deal and easy to use, especially if you are filming yourself.
