You will find it useful. I use mine every time I run the machine now, even tough my computer is in a better location that previously, I still love having the bumpbar to get up close to the bit and be able to move/set/zero/etc the bits without having to go back and forth from the keyboard.
I wish I was there... but it is crazy at work, and I have a large kitchen and another case goods job to finish for next week.
