Time to get a film camera.

I think you've answered your own question:

Keep the K-30 because it's your second-best camera and that makes it the best option as a backup.

Keep the K-200 because it's worth more to you for sentimental reasons than to anyone else on the used market.

Keep the Kx because the hassles of selling it probably exceed the dollars you'll get for it.


I'm sure you'll find some use for these venerable machines. I've got an old K-10D with a broken aperture mechanism that I now use for mucking about with M42 lenses. And an even older Minolta Dimage A2 is now a dedicated sunrise snapshot taker (and occasional time-series taker). Or maybe you can scrounge up a cheap lens at a garage sale or thrift store and give one of the systems to a budding young photographer in your family or neighborhood.

I've never sold a camera. I wouldn't gain much money, and having a reserve is important to me. Several years ago, my then-primary camera. a Canon Rebel, unexpectedly died. I had no other digital camera, so I felt almost naked; not knowing what else to do, I purchased another Rebel rather quickly, then started doing research. This time, the Rebel lasted just eighteen months, but during that time I did some research and then purchased a Q-7 as a secondary camera. By the time the second Rebel died, the Q-7 had proven itself, so I was comfortable using it as my secondary camera, even for our second daughter's Masters Commencement {most likely the last degree to be earned by my immediate family}, until I found a K-30 I liked.

Sell all of them and pick up a used K5 ii or iis in the $350 range. The flagship products are just more reliable overall. You may find that your backup supplants the K70 just from features, wider bit path and the quiet shutter.
