Okay, I have had this particular item for sale for awhile and unfortunately, it hasn't found a new home. The set is brand new (I paid $240), but it does not fit on my arbor...I own a SawStop and the arbor is too short. I am not sure why SawStop opted for a seemingly non-standard arbor length, perhaps it is associated with its safety mechanism; nonetheless, for those that can use it, the Dial-a-Width gets excellent reviews. I am will to part with it for $140...it has never been used!
