If you ask five different pilots the best way to get a licence you will get six different answers. Many people opt to carry out training abroad and then convert their licences to JAR licences. The most important thing is that at the end of your training you have a JAR licence which will allow you to work as a pilot in Europe, whatever route you choose.
There are very few companies (if any) who will actually pay for your commercial training. Most sponsored schemes will require you to pay for your training but will have the offer of a job at the end provided you meet a certain standard.
