I'm helping a friend overhaul a 20 year old router. It's Nema23 (grossly underpowered at 150oz/in) and equally old Geckos. I'd like to just put on some bigger motors, but I know the PSU and geckos would be better served with an upgrade as well.
I was looking at this "all in one" kit here from Avid CNC: https://www.avidcnc.com/4-drive-diy-...ahcta80c3e2872
But I was wondering if anyone had any better kit to recommend?

Little info about the machine:
2' x 2 x 6" (XYZ), full size Porter Cable router head. Ball screws on all axis, 1" Thompson shaft and bearings on XY, 3/4" on Z. All aluminum (machined flatbar) construction. Dual ball screws on the lower (X) axis, using a single motor and timing belts to transmit motion.
Planning on using Mach3/4, if that matters at all. Computer choice is rather open ended, from old XP machines all the way up to Win10 new PC.
