Thanks for replay guys. I've already heard what I wanted to hear.
I know that Goldberg on Tower is for $320. The problem is that now I am working in Singapore and it's a different story here. First, ~ $600 US for Goldberg or another American kit is not a joke - it is real price that was given to me at LHS. I will not name them, despite that they even have a website with such prices. I think tIANci knows them too. Second, it is hard to ship such a kit by mail due to its size. And third, most North American on-line shops will not ship outside America. After being for a 5-6 years customer of Great Hobbies in Canada they have refused my order recently for above-mentioned reason. It was just a book. A year ago they shipped me my order here, but not now. The same with horizon, amazon and vice versa.
I am unable to understand this policy. Probably, it is pure American - Canadian issue due to well known events. I don't care actually. It is their problem. There are a lot of things to worry about these days other then some policy-making j....s.
Fortunately I can still buy on ebay.
