to add to the above, i will try price the machine you pointed to in parts.

New CNC Standard 3Axis TB6560 Stepper Driver Full Kit & Motor/PSU/Keypad/Display | eBay £ 165, may find cheeper--- motors,drivers, card, dongle ----RUBBISH

New WATER-COOLED SPINDLE MOTOR 1.5KW & INVERTER DRIVE | eBay the same i presume spindle £ 200

will find the B/screw and bairings pack later, but am sure i see these for 160 the lot.

Then you only have the metal on the machine to price,
