I recently put feelers out for an RFM playfield assembly for a friend (I'm still working with someone to obtain my NOS one), and while many people wouldn't take the risk with someone internationally for something expensive, I did and can report that it was a great experience.
Krisztián Forrai ('homebar' here on pinside), worked with me and provided up-to-date information every step of the way for an RFM playfield assembly which winged its way from budapest, hungary to detroit, michigan.
all told, it took just about a weeks total time for the parcel to arrive and then another 2 days to clear customs, but it was securely packaged and arrived just like the photos.
