I seem to remember seeing a device that would go into the shutter release - like a cable - that would accurately time long exposures (over 1 sec) with the camera in "bulb." Do any of you know of such a thing?

It's made by Prontor. Sells for $600(!) new from HP Marketing, and goes for about $20 on eBay. Works well.

Super-accurate timing of long exposures is unnecessary. On a 10 second exposure, you can miss by more than a full second and still be within a third of a stop.
