welliewanger makes a good point at the end of his post. If you do intend to go further with your aspirations in aviation, make sure you can pass a class 1 medical.
I have also heard on the grapevine that if a 'European' type NPPL is approved then the medicals will have to be done by an AME. At the moment AMEs are not allowed to conduct the HGV type medicals called for by the NPPL. No doubt the cost will then be on a par with the class 2 medicals of today.
