I found some at ReneHerse`s online shop and purchaised them. The bad thing is that he didn`t send me the payment instructions with the right shipping rates for europe and now they are out of stock as I see.
I wrote him at least 5 mails and never got an answer. Not very customerfriendly in my opinion if you consider that I purchaised already several items from them before.

If you see some on eb it would be kind of you to send me a link
