If canon releases a version II of the 100-400 then as the past has shown, it will be substantially more.
What happens when a version II of a lens gets released? the used prices of the version I go up.
the 100-400 is a pretty decent lens.
and yes, some people will dump stuff cheap because they don't care, need the money, or they just want to get rid of it.
no one here has used the tamron yet, and who knows it may not even a true 600mm.
I hope the tamron is awesome. it will be the perfect lens for my wife to use whenever we travel together.
