Ball screws I'm so naïve

As the title suggests what a idiot

I nearly made a big mistake, I was going to just buy some M12 stainless steel threaded bar 304 grade I think that’s right and have it machined to accept the coupling and end and support bearings with a M12 machined block as my ball screw.

But after doing more research on this forum I found that a purpose built ball screw is the way to go.

I am going to order my ball screw set from the above ebayer as most people on here seem to rate him for price but is the product any good and what is the service like

With one set of bearings for the x axis for now

Information and back up from a well supported forum is paramount
