I'm not sure if anyone has actually done an actual "hands on" comparison and or review of "alternate" meters (other than reading the individual specs for each meter). Not sure where you would find an actual review/comparison of multiple meters.
AFAIK, folks here have merely posted their thoughts on the meter that they own. You would certainly think that there would/could be a review & comparison somewhere on the WWW, eh? Perhaps some of the camera sites?
If I have some extra time to search around the WWW, I'll try and see if there's anything. If you find it first, please post your success? Thanks!
