If you shoot black & white you can basically do without light meter when you are outside.
If you still need a light meter, I suggest the following:
SBC (silicon blue cell);
Incident and reflected metering;
Modern, currently available battery;
Some of the lightmeters have an analogue reading (a needle) some have a digital display. Both solutions have pros and cons and the choice is personal. Digital display can be better if you are longsighted, they are probably more robust, they can memorize several readings and show them on the display easily, they can show subject brightness range. Needles typically show directly a series of aperture/exposure couple so they can be faster in real-life use.
I would avoid the very cheap Gossen Sixtino (selenium) as they badly fail in incident light metering. I also would avoid CdS based light meters.
That said, anything branded Minolta or Gossen (with the exception of the Sixtino) is certainly very good, and many other light meters are vedy good as well.
If I were you I would not care about the "vintage look". That doesn't mean that you cannot find a perfectly viable and functional vintage light meter, though. But I wouldn't restrict my choice to those.
