I've been considering getting a Pentax for some time. I've done quite a bit of research and still find myself unable to decide between 3 (all of which are available at the time of this writing). The three I've been considering are the K-1000, the KM, and the KX -- if anyone has an opinion on any of the three I would appreciate the input. Or if you think there is another that I might consider I'm open to that as well. I have leaned more towards the K-1000 for it's popularity and because it requires the user to think and learn more so than the others. The KX has more functionality, such as the DOF preview, and many pros recommend getting a camera with a DOF preview. The KM is just the in-between model. Thank you. All input is greatly appreciated.
