Hello,
Congratulations. I'm too in search after a P30 or P50 Pentax, being the less expensive Pentax film SLR, these days.
As an opinion, looking the specs, I would say that , except the imposibility to override the ISO (it is set by the camera, which reads the DX code on the film barell) it must be a good camera.
I found instead a manual:
