I'm posting this so people can judge what to expect in terms of quality from eBay vendors.
I purchased these very recently from "linearmotionbearings2008" via eBay (but not listed) after reading some good reviews not only from here and other sites but his high feedback on eBay.
While I wasn't expecting the parts (bearing blocks) to arrive like the shiny anodized look of the pics you see, I wasn't quite expecting this either. They are usable I admit.
In a word; Disappointing.
The ballscrews are acceptable even though one of them has spots of rust along it's length.
One runs quite rough/tight while the other is smooth. The tight seems to have "-12" engraved on the ball nut which would make sense.
You judge for yourself on the quality before you commit.
