RE: whitch camera
I have seen alot of nice pictures from all of the cameras you mention.
It boils down to how much you can afford and the amount of risk you arewilling to take leaving the camera in the woods.
Personally, for the money I like theI40, its digital, ifrared and takes video or still pictures.
I havehad my I40out for a month and each time I switch out the SD card, it is like X-mas, you never know what you will get a picture of.
