I have not been able to find a reasonable price for ballscrew wipers. Does anyone know of a source that sells just the brushes and not the full kit?

If not, I was considering buying quantities to get a reasonable price from someone like Carolina Brush, and selling them on Ebay in the standard sizes like 5/8", 3/4", and 1". Would anyone be interested, and if so, how much would they need to sell for?
