Well, I have used Norwood Director/Sekonic Studio  for most of my 
photographic life and still like them.  Influenced by its widespread 
popularity, I tried a Weston Master V for a time but never really 
warmed to it.   About 30 years ago I sprung for a Gossen Luna Pro which 
become my main meter.  Several years ago I lost the Luna Pro and 
replaced it with a Digisix that became my favorite.  Even after the 
Luna Pro eventually found its way home, the Digisix still gets the most 
use.  I like it for its compact size and weight, plus it keeps time, 
reads temperture, casts my horoscope and suggests stocks of interest.  
The Luna Pro and Studio still get some use, but spend most of their 
time in a drawer these days.  Adjusted for indiividual characteristics 
and used properly, all indicate accurate exposure and are easy to use.
