This Eagle is NOT a model kit but a die-cast collectible (fully completed and painted) model. It is made by an English company : "Product Enterprise" specialized in Gerry Anderson's collectors (UFO, Space 1999, Dr Who, Stingray, Fireball XL-5, Thunderbirds, etc...). Aoshima has just the rights for the Japan market but is not the manufacturer at all. This very cool item is planned for late january and is limited to 6000 units worldwide.
HobbyLink is selling the baby for $92.30 (pre-sold out).
If you want to save some money, you can order it directly at ProductEnterprise (UK - price is £39.99 pounds - it makes $73.40) :
