Don't get the Spec S, that's the low quality version
It has the plastic fixed camber links and stuff. If anything, just get the regular Pro 3 kit here in the US, you can find them around pretty cheap. And then throw in a good top deck and the HPI spur gear adaptor.
Also, I think the rcmodel site has shipping costs, maybe not. But it shouldn't be too expensive. I've ordered Pro 3 parts from Control Centre in Hong Kong and shipping was only about $6.00.
