Hi Baz,
I cant really answer that right now, im going up to Malaysia this week to discuss shipping directly from Malaysia with my Uncle.
Just FYI: Shipping from Singapore is about $45 SGD for a 1kg Air Parcel, but im not sure about volume limitations if you want a super long >1m extrusion
Good news is that everything in Malaysia is 2.5 times cheaper than in Singapore so hopefully shipping is too!
I'll let you know by the end of the week!
And I'll continue reading your very long thread.
