South Africa is where I was looking to carry out my PPL.
It was just dropping from R19 to the GBP and was around R17/1GBP.
Making R75k ~ £4,400
Now that the GBP is weaker again the exchange rate is around R13.5/1GBP
As seen here;
GBP/ZAR Currency Conversion Chart - Yahoo! Finance
R75K is over £5,500 and that's before you add the flight at £700 to get there.
Worth looking into though.
