Sawstop recommends you skip the Dadonator, which many think is the finest on the market. It has 6 tooth chippers, and the extra weight of the stack can damage the saw if you trip the brake. Another good one to consider is the Forrest Dadp King, though I think it may be some time before they ship again (Covid problems, I think). There's always the Freud Super Dado, I have one that's maybe 20 years old, been sharpened 3 times, and still cuts as good as ever. Another thing to consider is Sawstop doesn't recommend anti kickback shoulders on the dado sets. It might retard the brake shoe action. I think Freud redesigned their sets to accomodate that. With mine, after the second sharpening the guy ground down those shoulders to where they are kind of non existent now.
