The question of do you wanna buy or build always comes up.

Also, considder that your mill will use either a Gecko or Rutex so at
some point you will be paying the $$

Considder laying out what you will need for the mill, then use that
as a frame of reference for your practice.

Also, considder that when you pull out the old electronics, if you
can dissassemble them intack, and they are in good working order,
they can pay chunk of your CNC upgrade on e-bay.
