I am a skydiving instructor at Wonderboom in Pretoria.
AFF is for sure the way to go! Static line is outdated and takes longer to achieve a desired level of skill.
AFF is all about one on one instruction and learning in a safe, fast and efficient way.
The whole course should work out at about R9 500. If you have a look at http://www.para.co.za/
it will give you a list of registered skydiving clubs and qualified instructors.
The guys in KZN is at Cato Ridge. Last I heard they had issues with getting hold of aircraft and instructors. I would almost recommend you making a pilgrimage up to Gauteng and we'll pretty much get you sorted in a couple of weekends. have a look at www.tandemadventures.co.za
FYI: Manny from Icarus does not own a skydiving club, nor does he skydive any more. He still own a "school" in Edenvale, but makes use of instructors at different clubs. He will typically send you to Nylstroom (Who has no aircraft at the moment) or Witbank. You'll do better, price wise, to simply contact the clubs directly.
