I've just written another post so hopefully these appear in order...
Given the info from everyone & some of the responses from schools I'm not as worried as I was about getting the EASA while in the USA. I'm happy I can build hours in UK with an FAA licence, and £3000 with approx. 6 hours flying & some exams to get the EASA at a later date sounds okay.
If I can manage to do FAA & EASA at the same time that would be ideal, but I'd also need to see if that adds to the cost.
Thanks
