Not that aesthetics have no impact on me but I would prefer a modern digital meter with an AA battery power supply. It should read both incident and reflected and have a lock the reading feature. Compact would be nice too. Instead I have a Gossen Pilot I bought used for $9, good modern meters cost more than I can spend.
I kinda like the Gossen Digiflash it's small and portable and only weights 40g on the other hand from a design point of view I always liked the older Minolte Viewmeter 9 (Spotmeters).
My vote goes to the latest incarnation of the Minolta Autometer V1, the Kenko KFM 2100 http://www.kenkoglobal.com/kfm-2100.html it's the most versatile and accurate meter for film photography I've owned in more than fifty years of photography, it has so many useful for the film photographer they are almost too numerous to mention.
I am quite happy with my Zeiss Ikon Ikophot. Simple to use, doesn't use batteries and cheap enough to throw away if it should ever stop working.
