My two cents worth...
I have owned a second hand K200D (my first dslr) for close to 6 months and am still learning its limitations and strengths but I am satisfied with it.
Still, I went "retro" and picked up a *ist D (recently from here on PF) as a second body because of its TTL capability, I like its 6.1 MP, the pentaprism and the body feels good. I shoot mostly with manual lenses and speed is not an issue nor is the smaller LCD screen. I am aiming at concentrating on macro/nature shots with this one.
Really had I been able to afford it and available at this moment, I would have gone with another K200D. But the *ist D feels like a good purchase at this moment.
