Having done both N and VH ferry doesn't really matter which you chose. Both have their pluses and minuses.
However I endorse the idea of getting as much work done in the USA, except radios. Avionics in the USA is a nightmare and you will get SCREWED.
But anything else do it in the USA. As an example I got my 5 year undercarriage overhaul done their for $US9,000. The quote from Hawkers in Aust $20,000.
A big thing with all aircraft is to arrive in Australia will ALL inspections and ADs done. Then to have a workshop lined up for a fixed C of A cost.
