Hello Stefan, If you hold a current FAA class 1, can't you just do the renewal rather than an initial JAR? That was what I did in Germany pre-JAR.
Try some countries around Germany, you may be lucky... make sure you pay well under GBP100 for the initial class 1 and no more than half that if you only do the renewal (contacts on pprune).
As far as I am aware, you can fly other than N-reg in Europe with an FAA PPL (though those renting them out may have an issue).
Sure, you have already thought about laser eye surgery. Not sure what FAA says, but JAA will suspend the class 1 for a year - though this depends on the authority (can be as little as 3 weeks for the class 1, depending on where you do it...)
sorry of not being specific to the class 2, hope it helps anyway. IP
