1202 ball screws with flangless nuts?

does anyone know of a cheapish supplier of a 1202 ball screw with the same type ball nut with the outer thread?
I did message them in the link but still no reply.

if I get stuck theres always those in the link but I will need it machining one end for the bearings..any recommendations or offers on that?i know theres zapps but too rich for me.
the screw I need is to be about 250mm-300mm long to fit inside the small axis on a lathe,i did fit a 1204 ball screw but had to butcher the flange(grinder) on the ball nut to get it to fit...it works but it bothers me,thanks
