My D200 has just reached 85,000 shutters. And i'm starting to get a little nervous about how much longer it will last. I use my camera everyday for work, and i'm shooting my first wedding next week. When it comes down to it, I need a new camera. But i'm not sure if i should step up to the D300 or just get another D200. I have been extremely satisfied with my 200. The only thing that i didnt like is the noise at high ISO's. What are some of your opinions on the 200 and the 300. Would you suggest shelling out the extra couple hundred dollars for the upgrade. I have read a decent portion of the dpreview on the 300. What are some other things that you guys have noticed that you really like.
