so what's the benefit to having different screens? Also, I'm fairly satisfied with the winder on this camera, it feels pretty comfortable and I don't really want to put money into other winders when I'm fine with what I have.

I'm not sure about the backs and prism though. The backs might work well but I'm still not sure as to why I might want to change the prism unless it was just to take it off and maybe use something else like a loupe to check focus though it's a pretty small spot to put a loupe or something similar on. I think the 1/60 mechanical shutter w/o batter sounds good though.

I'm hoping to send it back today to probably just get it fixed unless I see that they have something that's similar that I could trade for.
