I have shipped in and out more than 75 pins since 2005. The only damage I have ever experienced on a "legs on" shipment to me was a scratched and damaged leg that they paid for without hesitation. I have never received a report of a "legs on" delivery that was damaged. I have had several instances of damage on a pallet, all of which damaged the cabinet or side of the head and required (at a minimum) re-decal. Pallets require forklifts to move, and forklifts and forklift operators are the pure nemesis of pinball machines. NAVL/STI/Beltman use man power to move machines in and out of the trucks. R&L Carriers is the worst for poking holes in a box or stabbing a cabinet with a fork, in my experiences. But I have had issues with all of the carriers when they use forklifts.
Just my two cents.
