Serfas bike transport case, I used for a couple of trips from Japan, worked great. Some details from the web:
Two Heavy Duty casters for mobility
Bullet proof Polyethelene shell
Internal straps and foam for extra stability
Two piece design for easy packing and unpacking
I was looking to get $250 for it, they are selling for over $300 on Amazon.
It will be shipping from Yuma, Az.
