Giant 20' x 3' x 2' router build

ok so for the long x axis to get the fast speeds zapp have recommended the nema 34 8nm motor SY85STH118-6004B Nema 34 High Torque hybrid stepper motor

but said that the EM806 drivers would not be powerful enough so it would have to be the 2m2280n driver which looses the functions we have been discussing unfortunately. 2M2280N Digital microstepping driver

from a users point of view is it worth reducing the speed requirement just to run the other drivers?

while i want to build the machine to a good quality i just need to be careful the costs down spiral out of control.
