There is a limited number of ballscrew items on ebay. What i did was constantly check every ballscrew related item until i found what i wanted for a good price.


I stay away from the used ones...you don't know what they've been through. My very first ebay ballscrew buy was a used C3 zerobacklash 2mm lead ballscrew...and i wasn't impressed with the condition (even though it looked good in the picture). I sold it back for about what i paid for it (or a small loss).
