I would consider Europe, but I have no intention of hiring a piece of junk in the States.
A shame you think that way, I know of a very very very well maintained (know both the owner and the guy who maintains it) C310 which you could get for around £110 per hour. Alas it's in the States, so you wouldn't be interested. Let's see, with a round trip airfare (on a British Airline of course) of around £350 inc tax, you would be in the money after a mere four hours too.
Try South Africa, they are cheap down there, and I understand they have similar maintanance standards to the UK (not unlike the place which more than likely issued the original type certificate of the twins you love so much).
