If I remember correctly, it's not feasible for Doepfer to make them anymore, so you have to either ask him nicely and pay just as much as for a 6U (possibly slightly more, I forget), or get one second hand. However, I just tried searching for the e-mail in which he said this and couldn't find it, so I could be wrong. Hope that helps, Zoë.
