I'm not in Europe but there were always a lot of them available on Amazon. I saw some today as low as 14.95 USD.
I have a few of the superheadz clones. The black one I like the most has a rubbery outer coating. Unfortunately the finder window is coming out I (ab)use it so much.
I never had an original model, but these definitely have a certain unmistakable 'look' to the photos.
Good luck in sourcing one, i'd try amazon, then FLEAbay.
