I have the Gossen Digipro F (an updated version of the Sixomat Digital) and it's light, pocktable is very accurate, has a nice narrow 30 degree acceptance angle, you can easily asses image contrast with it, it runs on a single AA battery you can get anywhere. I also have a Lunapro SBC that I've retired because IMO the Digipro is a better meter, I'm not into digital cameras but digital light meters are magic.
