Nikon 18 - 300mm Lens - Thoughts

[The Fisher King]

While on ebay looking at lenses I came a cross this -

This bloke is selling his Nikon 70 - 300mm lens becasue he is sick of changing lenses,so he purchased a Nikon 18 - 300mm lens or as he called it an all rounder.

I like this idea having two lenses in one although a little more expensive.

What do you think,your valued opinions please
