If you are paying for it yourself then you could do it in South Africa, about $3000usd for B200 and B1900, and they have a nice non-motion sim. I think the place is called 43 Air School but they lease it out to other instructors as well. I did a B200 "Rating" there, with the last company I worked for (they paid for it) and popped it straight on to my Australian Licence with a letter from the SACAA
Ground School for the kingair was 4 days using Flight Safety notes and an instructor named Ralph "someoneorother", it in my logbook somewhere. If you want any more details PM me
There was about 2 hours in the actual Aircraft, plus back seating another student for extra exposure.
