I concur with Mark. Algoa in Port Elizabeth is streets ahead.
Superb training in fab environment. Sociable and active flying school in non-profit club. Instructors / admin staff who go out of their way, and remain friends long after you leave for the UK. Quality of training that will stand you in good stead and is easily adapted for UK flying and licences.
Have a look at
http://www.uksa.flyer.co.uk/ for soem like minded people and look out for Irv Lee who is the link with all things JAA / JAR and SA etc.
All the best
