I think its important for prospective PPLers to know that training costs vary around the world, and for them to make the choice whether to go to SA, USA, UK etc. themselves by listening to others experiences and to make an informed choice.
The fact is though, if you can't spare a month to go abroad, do your licence in the UK (or your home country). If you can, then go abroad and have a great time....
