Give that you already have the PC, the total software/hardware cost to
implement +/- 10V control outputs to your servo amps and a quadrature encoder
interface for the PC would be almost exactly $1000 assuming you need 8 axes
or less. Three new amps could cost a lot more than that, especially if they
are to drive really big motors.
