i still don't get why people go through all this trouble when one can simply get rid of dust and scratches through photoshop or another image editing program. In my opinion, it's not worth taking a risk.. I'd rather have a dusty camera, then a scratched one. Plus, I don't have surgeon like hands.

I clean my sensor regularly with no problem. It is a ridiculously easy procedure. I would rather spend a couple minutes cleaning than hours going through a set of 500 pictures cloning out dust spots. If you shoot a lot and change lenses outdoors you will get dust on your sensor. Unfortunately the cleaning companies like Copperhill prey on peoples fears and sell lint free clothes on a stick with a bottle of methanol for radically inflated prices.
