this is the reason why some of the seniors are unhappy with Nikon's marketing style.
But my belief is that the D5000 was targeted at the entry-level crowd to buy mainly the 18-55 and maybe the 55-200. You are one of the rare ones that is looking for the more 'unusual' lenses.
Seriously... to pay S$1.4K for (which lens?), the Nikkor 10-24 DX looks like good value.
