Hi WD,
Two ideas:
1. do a quick search in this forum, or the Wannabes archives - there have been quite a few posts on flying in SA.
2. Have a look at the <a href="http://www.avasp.com" target="_blank">Aviation Aspirations</a> website; the section on Training Overseas has some useful information.
I did my PPL and Night Rating in SA last year, and I've just started flying on it in the UK. If you've got any questions that aren't answered by the other two sources, email me offline and I'll try to help.
By the way, whereabouts in SA are you? Amazing country, isn't it!?!
