Hard Sided Robot Transport Case

Does anyone know of or have a good source for hard sided cases for transporting our robot to competitions? We are not looking to build one, we would rather buy one that is suitable for transport in a commercial airline cargo hold.

Thanks

You look at these

We use these:

You can get casters (easily removable/storable for flight), so the team also uses it to go back and forth at large events like worlds. Makes a good seat too :wink:

They are expensive, but we have had ours since Worlds in LA with no issues at all. Built like a tank.
