hey,i know the avaliability of the 18-200 is virtually only avaliable with a d200 kit. i was wondering if anyone woudl be generous enough to offer a recently purchased or brand new 18-200 that works well. the reason that i need this so badly is that i plan on going to africa in june and i need one asap. please help me out. i can pay 750-800 for a brand new lens, and 700 for a lightly used one.
