irreparable damage with poor quality FAA training
Good point Big Grecian, however not all training in the USA is poor.
There are plenty of good, very good and excellent schools in the US where there will be no problem with conversions.
Especially if the US school in question has been kind enough to emphasize things such as ADF/NDB.
Remember you can find poor training everywhere, also in Europe.
Problem is that quality and cheap very rarely, if ever, go together.
Problem is for a lay-person to have to decide to go for a 40K school that will turn out to be a 70K school by the time they are done vs a 70K school from the beginning and ending up within budget.
