I would hate to put a dampener on things but it might be prudent to give her the money for the coffee machine & let her buy one that has local service over there.
That said, if the options over there are limited then undoubtedly the best way to go would be to recommend the simplest technology..which means simple, tried & proven such as good ole boiler technology...
eg, Silvia (as being the "best" simple machine even if you have to spend a little more than $700.00). Othwers are cheaper, but dont compare for whatever reasons.
Mind you, Denmark is EEC or EU right? So volatage should be fine (230Volt european standard), and really, coffee machine availability service should be good?
My 3 dollar notes worth!
