Hi Ju, its not me selling these cases, just thought I would share the info with people seeing as how an official case is not yet forthcoming.
In theory any case for the Sony 600 will be fine for the Elonex as they are virtually identical in size, but a lot depends on how the case holds the reader. If it has 4 corner holders its unlikely to work properly. Which case do you mean, the one i listed is for sony 🙂
