D200 and third party lenses.
I found out something interesting about the D200. I have a 3 year old Tokina 28-70mm f2.8 that I purchased for an N80, but it didn't focus accurately or quickly on my D100 and D70, so much so that I boxed it back up and put it on the shelf.
On the D200, it's like a new lens. Quickly focusing and very accurate.
