In my experience...
I recently bought a pass-thru Doll/Falk valve from Jutta and the
shipping was about $8. The valve was expensive but fits and works
and the shipping was inexpensive. A whole good sized engine might
cost $100 to ship. That is up from a year ago and is a tough nut
to chew. If I visited Germany I would leave my clothes there when
returning and fill up my suitcase with steam treasures.
