Rendegade, I just sold an engine to a guy in Australia. The current United States Postal Service (USPS) Global Parcel Post rates are amazingly affordable. I think it only cost $16 US to get the engine delivered in 4-6 days (UPS quoted $104.xx). As an example, Tower Hobbies charges $8 to ship across a few states.

My point is that you can easily buy engines from US sellers through ebay and get them to use USPS Global Parcel Post to ship it quick and cheap. Good luck.
