I forgot to mention this Kopil Self-Timer with straight threads...
Self-timers are very useful for Stereo Realist camera users... They allow
you to put yourself into the picture.
Most self-timers have tapered threads and they do not fit very well in the
camera's cable release socket. But this one has straight threads and fits
like a glove! Allows a 15 second maximum delay. Asking $35. You can see
it here:
