I really liked H's 24-105 when I used it for the
wedding I shot back in February.
It's got the great zoom range, and is useful for some landscape situations and great for widefields and conjunctions etc, which I love to shoot. It's also great for portrait and family shots too. I'm leaning towards it...
Eventually, I would also look at the 10-22 for widefield landscapes, and the 100-400 for telephoto stuff
