Last week I bought two different light meters- I was at a camera shop for work and saw a Sekonic L398 (which was my first meter- I still own but it's beat to shxt.) That Sekonic is still a fine choice and needs no battery- I paid $50. Later I went to a junk shop and saw a meter I'd never heard of a Tundra D-3b for $2. I figured for the price why not and when I got it home I put a new battery in it and voila... it worked fine. But truth be told, for much of what I shoot on film, "sunny 16" is fine, or when I forget a real meter, I have an app for my phone. Black and White negative film is very forgiving. However, if you ever plan to do any studio work- you'll need a flash meter. Or shoot digital and transfer the exposure data to your film camera. With vintage meters that use batteries, consider the price and availability of the batteries required.
