"shopped" around a bit more today
U.S various flying schools and clubs
(I think the lower prices do not include the fuel surcharge, which from what I have read can be anywhere between $10 and $20 per hour)
C150/152 - $56-90
C172(L/N/P) - $79-114
C172R - $129
C172SP - $100-134
C172SP + G1000 - $140
Australian Rates
C152 - $135 USD
C172 - $170 USD
South African Rates
C172(L/N/P) - $150 USD
So it looks like the U.S is definitely the cheapest way to go, accommodation is also reasonable at about $50 a day.
Bobby - If possible could you provide a bit more detail on your trip, sounds interesting. How was the C150 as a touring aircraft, have not flown one before, but being cheaper I would consider doing a conversion to one.
Are they in good condition and reliable, the 150/152 that i have seen all look a bit worse for wear, and generally lack nav equipment,
Anybody else have any experience in doing their hour building in the US
