I have a bunch of meters: a drawer full. At one point I thought it would be fun to collect them. A Weston IV is in the mix, which I don't really use much truth be told. Every now and then I take them all out and compare them to make sure they still work. The Weston is still right on the money compared with two Gossens. I also have an old Zeiss Ikophot which is neat though not sensitive enough in low light. Sometimes it is just fun to use the old stuff. When the old meters stop working, I throw them out. I should really use the Weston more. It is a heck of a lot smaller than the Gossen SBC I prefer.

In the end, the best meter is always your brain, just saying...
