I have costed a couple of MRS200 kits to the USA of America. Works out about £3500, but that is just to dump the crate on the quayside - the US buyer woudl have to sort paperwork, taxes which would be about £1500. Then take it home. ...which could be quite a long way! My enquiry was for someone up near the great lakes and it was 2 days drive in a van to New York to collect it! He decided it was too much hassle to make it worthwhile in the end.
I think you need about 10 kits to make it worthwhile.
