I have a Rostock Mini from 3D Printer Czar, but they took down the data (instructions, firmware, etc.) - does someone have that handy that they could send along? Would be immensely helpful!!
I think there are a few sources of Rostock Mini kits, you might be able to find instructions online from another vendor. I believe at least one other source is posted on Thingiverse besides 3D Printer Czar.
