I have a number of Mamiya C330s and am planning on selling a couple of them.
But I don't know how to evaluate the relative value of some of teh
accessories. I have both a prism finder and a "sports finder" that looks
like the prism but uses mirrors instead of a big hunk of glass. Which one
of these is considered to be the more desirable? Or perhaps the more
valuable? I'm inclined to sell the prism just because it is heavier.

Thaks in advance for any advice.

Both methods previously recommended will help you determine current value,
but not necessarily accurately, as condition is paramount and eBay can't hold
a candle to KEH in determining condition in my experience. eBay has a greater
fluctuation in prices due to the nature of auctions, while KEH is the
industry standard in grading of used items. I have personally received some
C330 items from auctions that would not have even passed KEH grading, so for
that reason I recommend KEH. I am not an agent of either KEH or eBay, just
sharing my experiences.
As for the "Sports Finder" you mention, I believe you are mistaken in the
nomenclature. The "Sports Finder" is built into the waist level finder hood.
I believe you may be referring to the Porrofinder which as I understand it
uses mirrors to orient the image in the viewfinder correctly. My Prism Finder
image orientation is upright but still backwards right to left when reading
the data off the focusing screen. Hope this helps.
