After spending $1200+ buying SBR Rails, ball screws, 8020 components,alum Z axis and countless hours in research on this forum; I've decided to order a CNC Router Parts Pro 4824. At this point in my life, I just don't have the time or patients for a drawn out trail & error build.
I elected to go the 4824 route because of the extra rigidity and future expansion to 4848 or larger. Initially I plan on using a PC 3.25 HP router I have new in box.
If I can sell the components I've purchased at a decent price, I will buy a spindle/VFD package.
Now the wait for everything to arrive & start assembly!
