A priority flat rate medium box with insurance for $150 and return receipt is $55.05

If you do not add insurance...the international flat rates have a default of $127.50 (in some situations built in) for insurance:

Indemnity is included for uninsured parcels, but it is limited to the actual value of the contents or, based on the actual weight of the package, a maximum of $127.50, whichever is less. Indemnity is not provided for certain items. You may purchase insurance based on the article's value for coverage up to $1,429.00. When insurance is purchased, it replaces the indemnity. Certain valuable items must be insured. Consult the International Mail Manual or your local Post Office for detailed information.

Not sure if small electronics are covered in the above. The difference...would only lower the postage (w/o paying for insurance) to $47.95

I will be having a brand-new EPL1 coming in a bundle (I really only wanted the bundled lens) and it will arrive in less than a week, if you are still looking for one, let me know

Two weeks ago had a EPL-1 body only, battery, charger, shipped First Class International to Thailand. Cost $22 which comes with $400 insurance coverage. Having them weigh the package and ship First Class International in my case was cheaper than a flat rate package.

I did have the package shipped to a friend's house in the states and had him mail it. Shipping was free. It may be more expensive to have a store ship it straight. Not sure.
