Well, I've bought the bookeen cybook opus.
And I guess I'm not gonna regret it. Simple , clear text, and faster then I expected!
They also had the bebook mini and some more expensive devices.
But they only had the book mini left in white, and the exposed device (which was also in white) was already dirty, that added to the fact that the cybook had a leather (like) sleeve, made that I chose for the bookeen.
I bought it for 220 euro.
Thank you all!
