Sairfan 1 - I have converted an Isel router to Planet CNC and found the process quite easy. I am no machine builder and if I can do it, must be easy. I moved from Mach 3 and find Planet CNC far better. The new TNG software still has a few minor peripheral bits to resolve. But which controller system on the market does not? I particularly like the Warp feature and use it frequently to engrave on irregular or 3D surfaces. I believe it was originally developed for PCB work.
