The availability of N-registered aircraft on the European market is also very limited and ferrying one from the US to Europe will probably not be worth it. At least not for an airplane in my price region, which is around 30.000 €.
For some types (e.g. Mooney) it's just the opposite - the vast majority of inexpensive Mooneys on the European market are N-reg, which makes them a big hassle to register under EASA.
