I doubt that you will find someone who owns/has owned both cameras.
People who buy DSLR cameras tend to stay with whatever brand they start with.
When they invest in several lenses they are not likely to buy a different DSLR camera and then have to buy a whole new set of lenses.
Find the camera that has the features you want and you can afford.
Go to a camera store and get your hands on that camera.
If it feels good in your hands - that is the one for you.

I was just curious if anyone has had experience with both the Canon EOS 40D and the Pentax K10D and could explain which one they think is the better camera out of the two.
