While generally yes a normal router has more runout, Velox has a special spindle collet(looks like an ER collet) that eliminates most of the runout issues. It is louder and the torque can be an issue, I will agree with that. If you really want a proper spindle, buy one from China for 200-300 dollars separate from who you get the machine from(we will probably be doing this for next year).
