18-200mm lens for Nikon?

Hi, I need some help finding a lens.

I'm looking for a 18-200mm lens or a similar length. Doesn't matter which brand and I'd prefer not to go over $300… Used, New, or Refurb.

If you wouldn't mind posting the brand, & name or a link, it would be most appreciated!

Any help would be fabulous!
Thanks!

Added (1). I'm a photo journalist and I already have a 55-200mm and an 18-70mm but can't keep on changing lenses when I need to be taking an "earth shattering" photograph. I need sharp focus and good color like my 55-200mm. I may be willing to spend a little more if I find a good lens.

I really appreciated everyone's comments

Tamron actually makes one within your budget

I would expect the quality to not be the greatest. If you can tolerate the extra bulk and lens changes, adding a Nikon 55-200mm VR to an 18-55mm VR could give you sharper pictures.

If you are investing in a lens for your work, and the 18-200mm on-demand range is what you need to get the shot, then I think you should adjust your budget and get the Nikon 18-200mm VR II.

Tamron AF 18-200mm f/3.5-6.3 XR Di II LD Aspherical (IF) Macro Zoom Lens is the one in your budget.
Pros:

- Quality construction. The lens doesn't feel cheap.

- Zoom range of this lens is fantastic.

- Image quality is great.

- Internal focusing makes using filters and hoods a piece of cake

- Zoom lock is nice so the zoom ring doesn't turn while stored or carried.

- Price. For the money this lens will give you a lot of bang for the buck.

Con:

- Auto focusing is a bit slow for a moving subject.
