What do you Hasselblad users use for prism finders. I just want to get an idea of which features you like/dislike about the various finders available. I have a 500c/m and I'd love to hear what users of this camera think.

Also, what do you think of the Kiev brand finders. Are they worth buying as a cost effective replacement for a Hasselblad finder?

Thanks in advance,
Ara
