Be very careful in accepting packages from UK based agents
That's a very sweeping statement. Do you have any experience of any other agents apart from the one you mention?
You also say that the best way to use training in South Africa towards a JAA PPL is to train to solo standard under SA rules then come back and complete in the UK. Unfortunately that's not possible. To obtain a JAA PPL you must complete a minimum of 25hrs dual and 10hrs solo in the JAA state which will issue your licence. So only 10hrs flown in SA will count towards the minimum 45 for the licence. When you take the air fare into account it's not worth going to SA just to fly 10hrs.
