Try DHL... they are much cheaper than posting.
it cost me AU$110 to ship a tube 1500mm long X 120mm.. weight approx 5lbs. ( just over 2kgs)
Where you get 19lbs from ??? that right there will be the killer Surely it wasnt populated?
No, it's empty. Does seem heavy but it is a big playfield, and I'm sure they've shipped internationally before.
