Quoted from GroggyFrogFace:
This is KMS Handels so I will save you the message - they don't mail to the US.
However, if you're willing to pay, you can ship it to a third party, like mygermany.com, and go that route. I had to do that for an I/O board I needed which I only found at their store. It's safe (and legit), but it is pricey (especially for a board that's not all that expensive). It took about two weeks which I thought was quite reasonable especially during another Covid round, and the transaction was very smooth. Both KMS Handels and MyGermany were very easy to deal with.
If you think the board is messed up, you may want to contact Marco and see if they can get it directly through Stern, or you can reach out to someone like Chris Hibbler and see if he can repair it.
Unfortunately, you are correct. KMS will not ship to the United States. I would wonder why this is their policy. I was able to get my pinball tech to bypass the damage traces and pads and get the board working. It is a bit of a tenuous fix and I would want to replace the board. I will contact Marcos directly. They do list it as not in stock and I did give them my email information. I do appreciate your suggestion to use a third party shipper and it is an expensive way to do things.
