I had to move my Beast Wars and Machine Wars collection from Japan to Australia. That was _not_ cheap. I would recommend starting as early as possible and shipping your toys off in lots.

I cannot imagine moving my entire TF collection overseas though. When I moved to Japan I just packed all my G1 and G2 Transformers into boxes and left them at my parents house... but of course I understand that not everyone may have that opportunity.

It's hard enough just moving my Transformers across to another suburb!
