I had no trouble buying from
http://www.mobiebook.com/buyezreader.asp a month or so ago (click on add to cart). So far as I know this is still only available in black. It is a standard Hanlin V3 with the standard Hanlin V3 firmware, see
EZ Reader: Initial Impression. I think BeBook also uses essentially standard firmware. The firmware is interchangeable between the two.
You can buy a BeBook from the US, and it is currently a bit cheaper than the EZ Reader. You would have to return it to Europe if it breaks though.
I think the Hanlin V3 is the best 6" EInk reader out there currently, but all the major devices are "good enough" and none is even close to perfect. The Hanlin supports the most DRM-free formats, but you may end up converting to a single format anyway because FB2 is supported best and MOBI is also ok (and DRMed MOBI is supported). Calibre can convert just about anything to MOBI or LRF/ePub (for the Sony's), and you can try this on your PC today. For conversion to FB2 you can use Book Designer (Windows only), but it has a steeper learning curve that Calibre.
