It depends what kind of PPL you are looking for JAA or FAA. Most of those offering JAA/CAA PPL's in Florida I wouldn't touch with a barge-pole. If you;re happy with a FAA PPL there are loads of good US schools who are not sausage factories for foreigners.
CaptainCrunch - again the same applies, there are no JAA approved PPL schools in SA. Once you have the SA PPL you will find it exceedingly difficult to get a medical renewal in Europe and very expensive if you can. Also there are very few EU based SA Instructors to do your renewals! However there are plenty of FAA approved AME's in the EU and UK and plenty of FAA licensed Instructors who do your BFR's.
So think carefully before either of you make the wrong decision!
