I have two k1000 bodies that I've shot with for 20 years. They're indestructible. Plus several lenses.
So the quality of what they make, plus that I can use my manual lenses with my k100D, and that the anti-shake feature is in the body rather than the lens (so I'm not buying this feature over and over) made it practically a no-brainer.
I have to go full manual when using my old strobe and some lenses but so what? I'm usually not in auto anyway.
Like some on this post, I did wonder if all the Nikon and Cannon users knew something I didn't.
But nope, just like with the k1000, I'm delighted. Now, if I could just get my hands on an ultra-fast, 18-200 lens that I could afford...
