Don't have the t-shirt as I did mine in the UK, but I did do some flying out of Wonderboom last year and if I were doing a licence from scratch I would definitely do it there.
It's unbelievably cheap (both to fly and to live), and there's an enthusiasm lacking in many UK schools. Please do a search because many of your questions will have already been answered on these forums. The guys on the African forum are extremely helpful and will not only answer any new questions but might even open some doors for you.
Of course there would be work to do once you got back, but as a head start, an hours cruncher and a confidence builder SA would be great.
If you do go, and feel the need for a break from flying, a trip to Robben Island from Cape Town is a remarkable experience and will definitely give you something to think about.
Have fun
