Some years ago I got an FM 10 with its original kit zoom for some small amount (10 or 12 bucks I think). It had a winding problem that turned out to be a loose part that I fixed by taking the bottom off and screwing something back together. I found its operation quite decent, and the exposure etc. quite good. I always wondered why this little machine was so less well regarded than the Pentax K1000, which is quite similar but lacks a timer and stop down button. Even the cheap lens, while nothing to write home about, performed pretty decently. It seemed most comparable to the low end Yashica, but unlike almost everything Yashica made, the leather on the FM 10 did not turn to gray flannel.
I can see why Rowell would have liked it. It gives good images with little fuss, and it's almost entirely expendable.
