The Taig is the more robust/stiffer machine, but as you observe, the
Sherline has the better motor. Solution: Order the Taig with no spindle
motor, then buy a Sherline motor/speed control & fit it to the Taig, using
the Taig pulleys. Gives a speed range of dead slow to around 15000 RPM
(faster than the spindle bearings are rated for).

I believe I have hard of someone adapting EMC for the Taig; the controller
has a "phase drive" interface rather than the more common "step and
direction", so it needs some (software) tweaks to make EMC handle it IIRC.
You might consider going for the "CNC ready" mill and fitting different
driver electronics (for example, a Xylotex board) if you are going down a
different software track from the standard Taig setup.
