Harbor Freight - Gems and Junk

I bought one of these and it works well, except the slide hammer started going south. The little piece that "grabs" the weld-on studs doesn't grab anymore!....it just slides off! And without a good slide hammer, it's worthless. Hopefully, I can find a replacement slide hammer for cheap.
