In my pre importing comm's both USA to AUS and Shermatt were both nice to deal with. Helpful and polite and never a hard sell tried on me.
I did also hear that John Cain was good, I just preferred to use someone in VIC. In hindsight I wished I'd used any of them, (or someone else from the recommendations above).
However from my own very frustrating experience I can agree with the inclusion of the 2nd on the list of those to avoid that you mentioned at the start. IMHO very poor communications, months of unjustifiable delays, woeful organisation and an apparently total unwillingness to take responsibility for the mistakes and damages made by his chosen agents. (not to mention stiffing me on the insurance claim for shipping damages...).
I travel for a job, (inc. to where my car was), and have done a bit of overseas shipping before. And I am sure I would have done a far better job on my own, and now wish I had. I could go on... But I won't as I don't want the administrators to have more dramas over him. Apparently he is happier to expend resources on lawyers to threaten the MOC forum, instead of fixing his mistakes. (or preventing them in the first place). I am still having problems with him months after belatedly getting the car and the next stop is the lawyer. (BTW anyone reading this whose had similar problems I would be happy to hear from you).
I searched for him here before I signed, but alas the numerous posts on this business had been taken down by administrators due to threatened legal action. All I can say is - be warned! Anyone who wants details can PM me.
