The Big Hasbro falcon is $100 where I live, I thought about getting one, but the X Wing is the focus. They are both okay bases to build from and mod, I really don't see the playability for a child, there's little interactive value, still they are cool.
i just purchased the 30" x wing and big falcon on eBay Australia on the Target shop to be delivered to my nephews in Darwin. The big falcon was $59 + $9 postage Australia wide if your interested. The x wing was $49.
