Hi all,
I hope this is more appropriate in Accessories than in Flash. I want to get a motor cord to fire my 40D by PW (the CM-N3), but definitely can't justify the price tag for the genuine part. Does anybody have good or bad experience using third party cables? Specifically, this is the one I am considering:

Also, do I understand correctly that the pre-trigger cord (CM-N3-P) simulates a half-depress of the shutter release by always activating this (AF, exposure, or whatever it's set to)? Would I then have to set the AF mode to AI SERVO and just hope the subject is within the focusing point? Seems like more of a challenge...
So, since the radio triggers available on ebay are about the same price as the 3rd party motor cord, and half the price of a genuine CM-N3, would there be any real benefit to the motor cord at all?
