I have had a Kindle Touch imported from the US before they became available her. I also bought the Amazon cover for it, with a readig light built-in, and it does everything I want. My first EBook reader was a Sony which was okay but not as good as the Kindle, though admittedly Sony have released better readers since then. I stick to the Eink readers as I find them much easier on the eyes.
Kobo and Nnok also make decent readers though I have not used either of them. Each of the Vendor's try to lock you in, but at the moment all of their DRM schemes are trivially removed, with the exception of Apple's, which changes frequently. Once DRM is removed, conversion between formats is then easily accomplished for most ebooks. I would recommend the mobile read forums for further information.
