I have recent experience shipping an engine from Germany.
The costs have moderated a bit for smaller packages, but
they are all being sent by boat. Expect a 6-7 week wait.
I try to have only one package in transit at a time.
Packages over 2 kilo are still expensive and also slow to
complete the journey. While waiting, steam an engine
(put it out there for us to see!) and keep your sunny-side up!
