OK so ffordes are knocking a whopping 70 quid off Nikon and Canon fit MZ54i flashguns:

My question: does anybody know if this model will function as either master or slave to a 550EX? I know Canon flashguns are not the easiest things in the world to get to talk to 3rd party equipment.
another 550 is like gold dust and 580 is just too much cash hence my interest.
