I went through a similar decision process not long ago and elected to go
with exactly what you last mention. That is the EF 70-200 f2.8 L IS USM
plus the 1.4x converter. The lens is extremely sharp at all focal lengths
in the range. And being able to shoot at f2.8 is a real plus in low light
or for portraits where shallow DOF is desirable. With the 1.4x converter
only one stop is lost and full auto focus and IS is retained. And, the IS
*really* works! A negative about the lens is that it is fairly big and
heavy. Since it does not move when it zooms it is essentially at its longest
zoom position all of the time. I occasionally use the lens as a walking
around lens; when doing that it gives me a workout (I also use it on a
tripod a lot). I won't really knock the 100-400, but I don't like push-pull
zooms that much. If I wanted a 400mm lens I would probably go with one of
Canon's primes in that focal length.
