Both meters have their place. The Weston is compact & has lots of information on the dial, The Gossen with the null indicator & 9V battery is fast & accurate with an extended low light range.
Just one minor caution about the Profisix/Luna Pro SBC.
A couple of years ago I took mine in to a repair technician to have him perform the meter equivalent of a CLA.
I figured after 30 years of dependable use, my meter deserved a "spa day" .
The technician mentioned to me that it was probably a good idea to do so, because they were starting to encounter some part supply problems with Gossen meters of this vintage.
I also had a shoemaker repair the hinge on the leather case.
Everything continues to work great.
