Here is a spreadsheet for setting up the shooting menus, I started with these settings and after you find your way around the camera you can modify as you go. I mostly shoot in Aperture Priority, set the ISO according to the light the snap away. I need to look at how many actuations mine has on it but pretty much daily use, its been overseas three times and it just keeps ticking. Actually a friend loaned me his D700 for an indoor shoot and it is a lovely camera but I missed my D200. I have friends that are pro studio guys and they have both D200 and D700's but consider the D200 their workhorse cameras. I also have a friend with a D100 & D70, just solid cameras that last and last.
