Captain Crunch
The April edition of Flyer magazine (UK) has an article entitled "Six aircraft under £15K".
Unfortunately, the article only deals with 'direct costs' for each of the selected aircraft, and doesn't attempt to calculate the true cost of ownership, but I think you will find the article interesting reading.
Have a good time in SA! Make sure you allow plenty of time to hire and fly while you're there. The cross country opportunities are superb and the landing fees negligible (Cape Town International was 67p when I visited two years ago and parking for 24 hours came to the princely sum of £1.30, including tie down of the aircraft by apron and car to and from the 172!).
