Thank you all for your answers!
So I had a look at what was available for Europe on the amazon.com website. I'm not overjoyed, but it seems reasonable. So I'll keep looking up a bit and take some time to think about it, but I might give in and buy one.
I'll have a look at the threads on going around geographical restrictions, but I've kind of become allergic to them when I was using my cybook (I stopped using it about a year ago), so they would have to be _very_ simple for me to consider using them.
