I currently have an old Weston Light meter and from the discussions it seems
that some of the problems that I have been having with exposures seem to do
with the non linearity of the meter in low light.  It works pretty good in
normal light but it seems to overexpose in low light.

Can someone tell me what to look for in a newer used light meter that will show
that it is more likely to be linear.  I tested the older meter against the one
in my Canon camera (built-in) and it seemed OK, however I didn't test it in low
light.
