In the past I've bought and sold properties in Euroland, and used a FX broker called Baydonhill in London. They were very good, the rate they gave me was better than my bank could and only charged £20 or £25 to transfer 6 figure sterling sums. I've not used them for a couple of years, but if they are still around, I'd happily recommend them. They guy I used there was called Bruce
