Jack should be able to provide a shipping cost to your closest airport or shipping port. I'm sure he would strike a deal with shipping companies for TRANSPORT to your country, but after it lands, it is completely up to the buyer to organize. From my experience of importing single machines, shipping prices are given, but not to your door. You need to work out the rest yourself. So there is no way Jack or anyone can accurately quote a shipping price to your door. That is impossible.
Fumigation is a risk with second hand goods. New items in boxes are rarely fumigated unless the boxes themselves are on wood pellets that do not meet AQIS standards. I've had containers with pellets that meet AQIS standards and specified it on the DOP. It went straight through. I don't think a container of NIB would ever be subject to fumigation unless the paperwork was missing. But it would be inspected, not fumigated - unless the inspection found timber, straw or bamboo. Not one of my imports has ever required fumigation. Customs don't randomly pick out containers for fumigation purposes. If the paperwork is not completed, they may let you go - depending on a number of factors. "Country of origin" is another reason that affects fumigation. Asian countries with imports that have furniture made of bamboo will be fumigated regardless of the DOP stating no wood was used for packing. As soon as AQIS find bamboo or straw - you will have the container fumigated.
X-Ray of a container is random. Inspection of a container is also random. My Freight forwarder is brilliant as they have an AQIS Bay in their yard. The container is taken directly off the ship and transported to my Freight Forwarder. I have 10 days to collate all the paperwork. If a container is left in port, then the chances of AQIS sniffing around your import increases.
Although no import costs are the same, dodgy freight forwarders will add all sorts of costs. If the Freight Forwarder is more of a commercial importer, then they will rip a private import at commercial costs. As soon as I found a good Freight Forwarder, my landing and processing costs almost halved. There are also Tariffs which reduce the duty, or remove it completely.
There are a lot of tricks to the game of importing, but from my experience, there is no way anyone can accurately predict the transport costs to your door. Different countries have different rules, standards and costings. It is not up to the manufacturer to predict the costs for each country.
Having said that, I would be sure that Stern distributors look at the maximum price of landing the machine per unit and charge that to the customer regardless of the actual costs. This would be common practice in any industry. That would be based on feedback from distributors after the games have landed over time. They work out the maximum costs to import, and pass it on to the consumer. If the cost is less, then the distributor would keep the difference.
