There are generally two (three?) kinds of M42 adapters. The Pentax original one and other brands. The Pentax one will always be your best bet as it doesn't have a flange (allows focus to infinity) and is easy to remove wth fingernails.

Other brands may have a flange (some does not) and therefore cannot focus to infinity. Some of them needs some kind of metal sheet to remove as well, not as convenient. Although I've heard that to convert an M42 permanently to a K mount, you'll need the other brand types (? not sure).

In short, get the pentax original one unless you're planning to convert it to K-mount.

just in case you want to hear words of reinforcement, get the original one. don't settle for cheap ones that will give you problems in the future.
