I'm not sure why you are going with the Kindle when you don't live in the US? The BeBook and the Cybook can both access eBooks in Mobipocket (DRM & non-DRM) format which can be purchased from various eBook retailers around the world. Do you have examples of the eBooks you are looking for which can only be found at Amazon? Have you checked any of the other
eBook Retailers in the Wiki to see if they have the same title?
