See my comment (third post in the thread) about my K110D. Although I accidentally got a K70 as well, so the K110D is rather disused now.
The full story is that I left the K30 and some other kit, my passport included
in a café in Köln HBf. I was rather upset. My wife kindly bought the K70 as a replacement for my birthday
Then, several months later, the café owner got in touch to return my bag, K30 included
I really don't take enough photos to justify two bodies, let alone three, but nor would I consider selling them
