Watch out if you're doing your training outside of the Netherlands and especially outside JAA-land, they're very touchy about it. I had a Class 2 medical arranged and they cancelled it at 2 days notice when they found out I would be training in the US, and they weren't exactly polite about it either. Quote: "We stick to the rules here. If you will be flying in Holland and you want a medical in Holland then you also have to train in Holland".
If you can read Dutch check out the Piloten Forum for discussions on medicals in NL:
