CNC Mill Help?

Hi Guys

I would like to setup a small Milling machine to full CNC control and
was wondering what you guys recommend? I want something a little bigger
than the Taig or Sherline units. Is there anything available that
doesn't need the lead screws replaced with ball screws that has some
decent accuracy?

I am thinking of using the Geckos Drivers with Servo Motors. What do
you recommend?

Thanks in advance for the help.
