Canon 100-400mm 5.6 IS Good?

I'm thinking of buying a DSLR and the Canon 100-400 5.6 IS lens
seems like a good choice for the type of shooting I do ( wildlife ).
All the information I've found so far seems to indicate it's a good
lens. Does anyone here have first hand experience with this lens,
or any other recommendations? Since we're talking about quite a bit
of money, doing my homework first seems like a good idea!

Good news for you, Sigma has just introduced a new lens perfect for
wildlife photography. The Sigma AF 28-105/4-5.6 UC. It is the world
best lens ever made for any purpose! At first you may think that this
lens may seems to be a little too short for long range photography, but
you would be dead wrong, at least when used with either the SD9 or SD10
cameras. When used with either of these cameras, the 1.7 crop factor
make the effective focal length to be 58-780mm. While this may seem to
be a little long for taking shots hand holding, you would again be wrong
because of the built in image stabilization of the SD9 or SD10 cameras.
So in this case, you can have the best of both worlds, a wide angle view
with the power of a super telephoto lens. All you have to do is just
point the camera in the general direction of the subject and you're sure
to get it within the picture. Then just crop out what you don't want.
The end result will be sharper that anything you would get from the
100-400mm Canon lens. Also, if you set the 28-105/4-5.6 UC to the wide
angle setting, everything will be in focus up to 4" from the lens.
Not that the SD cameras have a problem focusing. So go with the SD10
or SD9 if you can find one, and the AF 28-105/4-5.6 UC, you will get
enormous depth of focus, wide angle of view, ultra high resolution, and
high magnification all at the same time. You can't go wrong with this
set up.

The Canon 100-400 L IS is an excellent lens. I've used it for the last year
with a Canon 10D with excellent results. Focal length on a 10D is 160 - 640mm.

Sigma 105mm.... Don't agree.

How does trhis work?
At best, the 1.7 crop factor would work out to a maximum 178.5mm long
end.
How does this become 780mm?

And exactly HOW does 105 * 1.7 = 780?
