Hi Mike..
It is normal.. We paid the same for the Mibo A-10 and the F104 from Modelbau. Got spoiled with F14 from Skymaster which was a direct delievery to the door step.
Between .. Broker fee, one time bond fee, document fee.. It all adds up to the $500.00... Then you got to see if you have to go to custom to pick up or they will deliever...
Let us know how it was packed and delivered.... I have one on order...
David
