Are you using a newer or older DSLR?

I have a trusty old Nikon D200 along with my 18-70mm lens, which is constantly mounted to it. I use it often enough, and it doesn't show it's age too badly except in the areas of battery life and storage format (CF). The body is in pretty good condition, and I'm definitely not scared to expose it to the elements. Both my camera body and lens are weather-sealed, so I trust it, although with some moderation (sand, etc).

My question is are you using an older or newer DSLR? And let me know why.
