Hey, I just got my 2006 grizzly catolog and theres an x3 in there for $925.
The spindle has 2 speeds, 0-2000 and 0-4000, I don't think I saw that before.
Its not the super, but the regular one,
travel on this one is:
Y - 5.75
X - 15.875
Z - 14.875
according to the catolog. It isnt on the website as far as my search went.
