I also checked several sites and indeed most of them give the 'not available' sign or have the page deleted.
But now I checked on amazon.co.jp and there it was/is still available.
I've ordered it approx. 45 minutes ago for €29,85 incl. shipping and handling.
Ok, granted it's not cheap but looks like it's the only option left.
Now the question is "will it ship?"
Edit: After translating the Japanese page I could read "Usually ships within 1 to 2 months."
Looks like this is a lost cause.
