Traffic costs are not at all "high" in the EU. Look at France, find a USA server as cheap as french unmetered and i'll award you a medal Bandwidth costs are however extremely high in the UK, and a few other countries.
Well...sligtly good bandwith in EU is expensive. And..i wouldn't trust ctn1.com with anything. I've heard to much bad about them. Actually rack365 is the only provider in EU with highbandwith plans i haven't heard a lot of bad things about. But bandwith prices in NL DE and SE are indeed not that bad..just not down to US prices yet.
