Im trying to figure this one out. I am seeing the refurbished ones sold by cannon, in kits with 2 lenses, going for less then what the "new" kits of the same thing are going online. Some amazon listings say the amazon listing is a "retailers kit made from canon factory components". based on the price of the camera bodies alone should I assume that the amazon retailer kits are also refurbished in some way? What actually lets you know your getting the version with the newest software updates? And what does expandable iso actually mean..
