I´m more of a lurker than a poster, and this will probably sound like a cheap commercial, but while i was goofing around i found a page that has the Shinkai 6500 is for sale for 50 USD (well, pre-order actually, it gets released in late February). I don´t know about the price, the other Legos they have are quite expensive. Well, anyways, here is the link:
http://www.amiami.jp/shop/?set=english&vgForm=ProductInfo&sku=TOY-IPN-2383&template=default/product/e_display.html
I have bought several times from that page, and considering i live in South America, it´s excellent. The Login/registration method is a bit counter-intuitive tough. After buying the item and clicking checkout from your cart, a page containing the Login/registration options will appear, just fill accordingly and you´re done!
After that you will receive and order acknowledgment mail, then a confirmation mail, and when the item is available, you will receive a ¨your order is ready!¨ mail, detailing the shipping costs. And if you love your wallet, select SAL small packet registered in the shipping field.
Well, c-ya!
