I send my Frame back to Germany (close to Austria – so figure its relavent) a month ago, i used http://www.bikeflights.com, who where excellent – i got an email at every transfer point and could track the frame all the way back to Nicolai, cost me £85 and that was tracked, 3-5 working days and fully insured for £2000
couple of things – the company is based in USA, so the time difference means they only reply afternoon evenining time, and once you have paid for the lables, they get emailed and can arrive next day so don’t panic about the little contact
in short everything worked perfectly and they even do round trips.
