From one who recently tried to have a very small appliance shipped from Germany (kaltmangel), am here to tell you under $1,000 USD would be a deal.
Depending upon the country, 20kg and 85cm long is about the most one can ship via postal system. Everything else must go by various shipping companies (same as FedEX and UPS), and there is where things get interesting. Moving large appliances really isn't something they do unless one ships the thing via freight, which is VERY dear indeed.
The item will have to be packed,crated, collected, and all sorts and manner of paperwork filled out, and perhaps export duties/tariffs. That just gets the thing to the plane/ship, once on US shores you could have customs charges as well.
Being as this may, there are services that ship large things from Europe, one can even order a BMW from Germany and have it shipped to the United States, the problem again is how much are you willing to pay?
Best method would be to get down on bended knee, like a gypsy in an airport and find someone moving house from Europe back to the US, and ask if they will allow your item in their freight. You can then arrange to pick up the item from them once they arrive on these shores.
Your other problem is going to be parts and or service for the unit. Some companies even though they have perhaps another product range in the US, won't give you the time of day if say you got an Electrolux unit shipped from Europe.
Unless the machine is a vintage model, make very sure the electronics and computer parts will work on two wire 220v/60hz rather than the standard EU one wire 220V/50hz. On timer machines things just run slighly faster at 60hz, however with modern electronics and computer systems things may run fast, very fast or not at all (sensing a fault).
