We all feel your pain and what a dilemma to have, I would have been over the moon with just a U1282A multimeter or a new set of Keysight leads, a 16 grand scope is a bit over the top for most of us amateurs, not that I’m knocking one back Dave….
I have very limited knowledge of the legalities in relation to gifts in our own country let alone those in others but is there any chance that you could get in contact with a local Keysight distributor and ask if they would be willing to exchange it for some other equipment of a lesser value and let them wear the additional costs, I’m pretty sure someone else also mentioned a similar thing where they simply didn’t need a scope of this calibre and would rather acquire a collection of other more useful equipment instead.
As mentioned I really don’t know whether it could be done or if a distributor would be permitted or even agree but it might be worth asking before receipt of the scope after which time you may be liable for the additional costs involved, better something less than nothing at all, also in the near future we may see a number of these turn up on Ebay in particular countries at exceptional prices where people just need to cash them in to pay for the unexpected expenses.
Others may have some better suggestions or even be willing to purchase it from you as AndyC mentioned above, either way we all congratulate and wish you well and hope that the outcome is satisfactory.
