Found pretty affordable option of F4 with 35-70 lens (don't care much on lens, I have my own good stuff), for around $200. In my region you can't find it cheaper if at all.

Met with the seller, checked and saw camera in real, and it was in much better condition than on photos. All seems to work just fine, even LCD was completely ok.

The only cons was the marks on the viewfinder and that plastic white piece like fell down little bit (pic related). So far found two repair shops, but they don't give me any even approx prices of repair. I don't know whether this white thing even affects anything, but it seemed to me that LCD was pretty hard to see as well as other stuff in viewfinder regarding exposure compensation, aperture etc., like you had to position your eye in a very specific way to be able to see it. Is this the case with all F4 cameras or it's just because of that broken part?

Anyway, judging by the photo is it possible to say that viewfinder was damaged like someone dropped it accidentally or something? In real life it looked pretty fine, seemed mostly like the surface has worn off but no visible bents or something like that.

Is it worth it? Functionally I really need this camera, it checks all marks that I need for 35mm slr, but my budget is extremely scarce and I'm torn apart and don't wanna to end up with a 1.3 kg brick after shooting couple of rolls.

Thanks for any advice.
