Or you could contact KJW directly and order replacement followers. They will probably be no more than 1$ or 2$ each and shipping is 2,50$ (from my experience with them in the past, their prices are VERY low when you order directly).
Their contact is:
kjworks@ms47.hinet.net
They sometimes take a few days to answer, but they always do. Get the part number from the manual, makes things much faster and it saves a few days of bouncing emails to confirm exactly which part you need.
