would suggest you either PAT or BCFT in Bournemouth, UK.
I would not suggest you to do JAA training in the USA, but do FAA training at first and then convert it in the UK or Spain. You can still spare some peanuts to spend on some sim hours to prepare yourself for an hypothetic interview after your training.
I agree with Gomrath - you can't really comment at this point Jerry Lee.
As someone who used to train FAA > JAA conversions I have yet to meet one who saved money when all was said and done and around 80% did them almost irreparable damage with poor quality FAA training - every heard of primacy? What you learn first, sticks to cut a long story short.
Ask any European instructor on their thoughts on conversions....
