When choosing which type of delivery, I will always choose Express Mail or Registered Mail because it is trackable, never accept standard non trackable post.
I wish the American web sites were more overseas buyer friendly at the checkout with delivery options and a reasonable freight price. Aircraft Spruce has such a great range of stuff and a great web site for ordering but no real viable delivery options for Australia at the checkout. I emailed them to complain and was told to list the items I wanted in an email to them and they would send a proforma invoice to me with the right freight cost (way cheaper then checkout one). Still took 2 weeks and many emails for them to get it right (the proforma invoice order).
I have ordered some things from the UK and parts of Europe without any problems, Freight was cheaper than from the States but items are usually dearer.
If I can get it from Asia, this is my preferred choice for price and cheapest freight cost. Vendors are keen to please customers, they know negative feedback hurts their business.
I have obtained a number of items through Ian on his Clear prop/Pilot store on this site and have not had any issues at all.
