Isn't the same as the one mentioned above?

I think the other post was referring to the Nikkor 18-200 VR. Sigma make two versions of their 18-200, the non stabilised one and the 'OS' - optical stabiliser. Sigma lenses are regarded quite highly, but in this instance the Nikkor lens might be the preferred option.
