We use iRemit. Have done for over 10 years.

Funny though, when we lived in Yokohama almost everyone we new (including my wife) used 'agents'. That meant Filipino's who just did it as a sideline.
We never got ripped off, but there were plenty who did.
I could never understand why anyone would give large amounts of cash to people they didn't really know.

I remember one Christmas time one of these agents (a woman) ran-off with over 6mill Yen which was over P3mill in those days.
I guess the amount was just too much for her to contemplate.
