I fell to the ground one day with my 70-200mm f/4L IS lens on a 1.6x camera hitting the concrete lenshood first, propelled by my 200+ pound body.
The lens hood was toast but the lens wasn't even dinged. It continued to work without a flaw.
I am not sure if either of the less expensive lenses mentioned above would have survived that accident as well as my "L" lens.
BTW: I personally would not consider the use of a 2X TC as a viable option with any lens. Although some photographers appear happy with the quality from the 2X TC; IMO the IQ is degraded far beyond what the naked lens produces - even on the 70-200mm lens. Additionally, if you are using a 1.6x camera, you cannot achieve autofocus using an f/4 lens with a 2X TC.
On the other hand I find that the image quality and auto focus of both my 70-200mm f/4L IS and 300mm f/4L IS lenses are quite acceptable when I use my 1.4X TC giving me a 280mm f/5.6 and a 420mm f/5.6 lens respectively.
