Which milling machine is suitable for whom?

XP007
Mobile small manual machine for drilling hollows and internal web keys. (No serrated ones)

XP005-L  
Small mobile electronic machine for automotive, inner track keys and serrated automotive keys.

Condor Mini Plus:
Faster than the XP005, also electronic and better for stationary use.

Flash Mobile:
Small mobile machine for serrated standard house keys and serrated automotive keys.

XC002:
Larger and faster than the XP007, but can't drill recesses, but can do lanes keys that don't go with the XP007. For stationary use

The bottom line is that in the low travel range, the main difference is whether mobile or stationary.

Mobile usually means a weaker motor, smaller displays and battery operation. Stationary is better for in the workshop, especially when you cut more keys etc.
