I've pretty much made up my mind to get one, but having others confirm that it's a wise purchase is a good thing.
In my bag I have a Nikon 17-55 2.8 and an 80-200 2.8 but would like to fill the "gap" between the two. You would also find a Nikon 18-200 in there, but it's focusing speed is measured with a calendar, not a stop watch. It's a great vacation and outdoor shooting lens, but just too darn slow for any inside work (like weddings and receptions).
Lastly, if you know of one for sale (other than eBay) please let me know. Thanks.
