What is a good split-image focus screen for a C-330. I'd prefer one that is
also brighter. My eyesight is preventing me from sharp focusing using the
Mamiya viewfinder.

I've bought a Beattie Intenscreen with grid and split-image focusing, it
is excellent and a lot brighter (2.5 f-stops) than the original Mamiya
screen.
