As far as I know, these are wonderful cameras with great lens able to produce excellent results...but I have one concern: Considering the camera won't have a sellenium meter working, how easy it would be to use on the very limited manual exposure setting?
Out of the two I had, only one had a non-working meter, so 50% chance of getting a dud. If you add the two perfectly working Pen EE-S2 I had, which are the Trip's little sisters, identical in every way except size, the ratio becomes 25%.

If the camera has been stored properly the meter will work, look for one with its original case, or a cap. Sometimes selenium cells are still alive but contacts get oxidized, and a little rubbing with an eraser is enough to revive them.
As for manual use, you can set aperture manually and the camera will use its slowest speed (1/40 I seem to remember, maybe 1/30), but there's a mod where you use a thin strip through a hole in the top to trigger the faster speed in manual. Look for it on Google.
