Shipping tube amps to Europe. What company to use?

Hi guys.
If anyone have an experience with that:
What is the best/cheapest way to send 2 tube mono-blocks (100 lb. Each) from USA(NJ) to Europe?
UPS gives me a quote around $500. Fedex is even more expensive.
BAX has a great prices, except they “for security reasons” deal only with companies.
I would appreciate your help.
US priority mail is much cheaper. However, know that it is a pain in the butt to file claims or collect on them. They will pay eventually but.....
I just shipped to Italy and it sucked.
