Hi
I did this year, i purchased the CRP2448 and put this kit on it and it works really sweet. The guys at CNCRP were very helpful with regards to using it too.
If you can get to you tube and look up Peter Passuello (cncnutz) he has a number of videos setting the spindle and the vfd up and i can vouch for them because thats how i set mine :-)
Enjoy Bernie
