Unless you know a mate that can knock up some some knurled rollers for you, the costs of getting them made up are prohibitive. I got a quotes ranging from $150 to $400(6 inch long ss rollers). You are better off buying and adpting a marga, or buying a mill from the US. Barley Crusher or Crankandstein would be the go. Luv one of the 3 roller jobs of Andrew's or Dicko's. But my 2 roller 2s crank still does the job.
