Please let me summarize your needs/desires for a new machine:
You have limited room
Want something larger and more rigid than your current machine
Must run on single phase 220 power
Ball screws
R8 or BT30 spindle
Maybe servos
Maybe rigid tapping
Controlled by LinuxCNC
Like me, you are elderly so not looking for a 10-year
project but you relish the idea of making designing
improvements and testing your designs.
Have you considered buying a new or used Tormach? Their 440 has a 42x36
footprint and an R8 spindle. Their 770MX has a 56x48 footprint, BT30
spindle, servos, rigid tapping, etc. All of their machines use PathPilot
which is really LinuxCNC with a pretty face. Factory electrics are fully
documented, there are many users willing to help with modifications and the
machines work "out of the box". They are more expensive than the initial
cost of what you have been considering but instant gratification has value!
Disclaimer: I have no financial interest but have been a happy user for many
years.

Neat, but does it have ball screws and room on the table for my converted
BS-1? It looks like the knee is all the way down and if its tilted chuck
facing up, probably a bit over a foot high.
