AMI WQ200 wallbox and stepper

Hello to you all,

Can anybody give me a price idea for a WQ200 wall box? There are a few on Ebay in the States at this moment, but I don't know what would be a logical price. From what I could read in this forum, it seems to be hard to find a stepper for this box, to go with a Continental 2. Is this true, where could it be found, and what would be a logical price for such a stepper?
Thank you very much for helpfull answers,
