As a rule of thumb you should be confident that a package can survive at least a 40 inches drop on an hard surface, especially for international shipping were lots of different people handle the package...
Edit: I reread your earlier post about shipping to Europe, that would be $41 then or currently less than 3 BTC if I'm not mistaken.
Oh. If it wasn't assumed, the units do come with mini-USB->USB connectors. I believe one isn't original, though, so if you were looking for a truly "authentic" experience..... SoL. (One was malfunctioning when I bought it, changing the adapter cable solved the problem)
France shipping:
1-3 business days, $79 for both
3-5 business days, $47 for both
6-10 business days, $38 for both
"whenever," $25 for both
Is the power supply modular (ie: is the 110V cable with American outlet adapter easily replaceable with a 220V cable with a French outlet adapter)? A photo of the power supply would help. Ideally there would be DC barrel to molex adapters (if the units use 12V which they probably do) I've seen someone selling hand-made ones but I'm not sure if they were meant to be used with Icarus boards.
