Clive,
Ah yes, but I'm a cheapskate. $270AUD plus delivery is a lot of money!

Part of the attraction of the G2Core project is trying out the reduced 'jerk' in the motion that it claims to have thanks to the complex acceleration calculations. How much of a real difference to anything useful this makes is, as yet, unknown, but that's half the fun. One of my reasons for making a CNC machine in the first place was just to see if I could. Even though I have since found plenty of things to make with it, there's still an element of that childish experimentation in the upgrades and changes I'm making.
