If you are looking for a low cost PPL, I chose Algoa in Port Elizabeth in South Africa in November 2002.
Under £2000 for 45 hours was about the best I could find - I have since found many other great reasons:
- I learnt to cope with windy conditions
- International Controlled airport so build radio confidence
- Very friendly (non profit) club
- Thorough course
- Game parks nearby
- Lots of aeroplanes and instructors - I passed my PPL in under 4 weeks and 48 hours.
- Don't have to convert to fly in UK
