CB Range discussion

I’m looking to get a separate cage for the CB6000 I already own. The official CB-X site has exactly what I need, but their shipping costs are $80 on top of that—more than the item itself! At that rate, it might just be easier to purchase an entire new unit. Since I’m based in Europe, maybe this is typical here? Does anyone know other places where I can buy just the cage without such excessive delivery fees?
