Both those Gossen choices were designed for mercury batteries. There are a bunch of very accessible solutions for using modern batteries in them. Here is one of many Photrio threads that talk about the issue: https://www.photrio.com/forum/threads/the-weincell-1-35v-px625-replacement.200663/#post-2705432
The Luna Pro is a great meter. It was one of the standard high end choices for a very long time. It does use a CDS cell, so there can be age related issues.
I gave away the last one of several I've owned over the years to someone relatively new at this. I expect they are still using it happily.
Gossen meters can be a bit confusing, because the US importer changed the name on a bunch of the models. If you see a Profisix, for example, that is the name that applies everywhere in the world except for the USA, where it is known as the Luna Pro SBC. That is actually the old meter that I recommend most - it uses an easily found 9 volt battery, and will work with a slew of special purpose attachments. It is slightly larger in the hand though.
