The only thing to be aware is that is gonna be a noisy machine at full revs

The noise will be coming from the tool spindle hardly any from the stepper motors/drivers.

To cut down the noise you need a water cooled spindle but they tend to be bigger in relation to the motor supplied with that machine so a water cooled spindle will not fit that machine.

Be careful of the shipping cost, the ebay machine looks almost identical and that would cost £746 inc shipping, plus any import taxes
