For the record, and perhaps assist your effort to sell this dado set...
I use a Freud Dial-a-Width (SD 608) Dado Set and could not be more impressed. Clean edges and very flat bottoms. The ability to fine-tune without the hassle of shims functions very well.
HOWEVER... My background is marketing and sales and in my view, Freud made and makes a huge mistake with this product. Using "Dial-a-Width" in its name was a colossal blunder. I contend that most woodworkers associate this phrase with the dreaded dial-type wobble dado, which simply isn't the case. As such, I wouldn't be surprised if a lot of otherwise interested folks dismiss it.
In any case, this is a first-rate product!! Too bad that Saw Stop compatibility is an issue for the original purchaser.
