I was having a browse on Aliexpress and came across several different USB breakout boards:

4 axis:

New 4 Axis USB CNC Breakout Board controller CNCUSB USBCNC 2.1 Alternative MACH3 #SM535 @SD-in Motor Driver from Industry & Business on Aliexpress.com
Planet cnc MK1 USBCNC CNCUSB USB CNC 4 Axis CNC USB Breakout Board Card Interface Adapter for Engraving Machine-in Motor Driver from Industry & Business on Aliexpress.com

3 axis:
A114A 3 axis CNC USB Card Mach3 200KHz Breakout Board-in Motor Driver from Industry & Business on Aliexpress.com

5 axis:
5 Axis 200KHz Stepper Motor Driver Breakout Board USB MACH3 USBCNC Interface Board for CNC Engraving Machine-in Motor Driver from Industry & Business on Aliexpress.com

I've sorted them price wise, lowest to highest.
I'm curious if anyone has tried any of them?
Do they look any good?
I might order one as an experiment, perhaps the 5 axis one. How bad an idea is that?
