Thom Hogan has a AF-S Zoom-Nikkor ED 18-200mm f/3.5-5.6G IF DX VR lens review. He says, in short, the product is definitely worth the $750. He concludes it's a "far better lens than you'll ever expect, even for US$750." He liked the optics and range of use. There were a few drawbacks listed in the review, including the variable aperture and some distortion.
It's a highly detailed review, but well worth the time if you're interested in this lens.
