I have flown out of Port Elizabeth and my experience was poor, it wasn't with the school you mention, I was purely hour building at the time, however the school I rented from did offer a JAR PPL and the English guys I met their were not that impressed with the level of tuition they were receiving, so think twice on your choice of schools. You also have to really watch the weather in Port Elizabeth, it was only when I arrived that I discovered that the locals also call it the windy city! This killed of the chances of getting of the ground for most of the month I was there.
I eventually had to dirve to Cape Town, I had intended to fly but poor weather put an end to that; There were some better schools I saw whilst out there though, take a look at 43rd AirSchool in Port Alfred, it has a good reputation and the facilities I saw were very good and the students I met were much more complimentary, I think they offer an integrated JAR course.
Good luck, if you have any other questions drop me a private message.
