I bought a monolta Auto IIIF years ago, I love it!. I bought it used at a photography garage sale, I think for less than $100. I have used it for all of my shooting for these many years and it still works perfectly. The only limitation this meter has is the absence of a sync socket for remote triggering.
For what it's worth.
I also agree with the find what you want and save for it principle.
Good luck with you meter search.
