Already decided on the 3.5F (evidence above) and I am really digging it. The mirror was also slightly dirty and dusty, but I cleaned that along with the matte screen and things are looking sweet in that finder now. I also found out that the self timer is indeed working, but the DOF-scale still seems unresponsive, is there anything I need to do to engage it? Likewise, I wonder what I have to do to disable that darned EV-thing that likes to kick in every time I turn the shutter speed knob towards the slowest speeds (the "non instantaneous" speeds) the camera hijacks the diaphragm knob and turns it all the way to 16, I don't want that, I want long exposures with a large aperture.
