Toon,
Unfortunately I can't help you on info about Brunnsum itsself or the trade/job, however, I've been in Europe for 18 months now and it's the best thing I have done. Without giving too much away I did 12 months not too far from Brunnsum and 6 months in my current post elsewhere but still in Europe. I love it, if you move away from the Military environment and imbed yourself in the local area it's great fun. You are not too far from anywhere, transport links are great and reasonably cheap and there is plenty to see and do. Some great cities nearby and further afield if you are willing to see Europe and not spend every spare moment wanting to rush back to the UK. I have lots of good things to say about being in Europe, obviously there are negatives aswell as with anywhere but if you would like more information about living in Europe then feel free to PM.
Good Luck with whatever you decide,
Daisy
