I wish Canon fan had been around when I bought my cable release dognabbit!
The problem is that Canon (and some others) have their own special connector so unless you have access to a) a machine shop or b) are willing to make a Rube Goldberg imitation you're stuck with buying the manufacturers item.
In all fairness the Canon connector is well made and the switch has the half down and a lock position also the wire itself is decent material but I gotta agree that the price is steep all the same.
