I don't know where you got your informations but they are wrong. You need to pass 14 written exams and you will have to convert your CPL/IR by going through a conversion course that's at least 30 hours. On top of that the European schools don't use Cessnas to do their professional course, plus gas and instructors being more expensive, that gives you the reason why it would cost 35K.

The JAA conversion is a little bit far away from 2 papers and acouple of hours in a Cessna.......
