EGO , about the cheapest , used them heaps of times , never a problem ( yet !)
There seems to be horror stories from all the carriers .
My tip , wrap with plenty of padding and then some more and then cardboard on the outside . Its worth slinging the seller an extra $20 for heaps of padding.
Write your name address and ph no on package with big fat texta.
Take detailed pics of the board before wrapping and also after wrapping .
