I've decided to try it and for less than $100 ($69 for the unit and $10 for 50 tenons) it either is or isn't going to meet my needs. I kinda look at this as an expensive first step toward the Domino.

Just so you understand that it's a *really big* step from this to a
Domino. I'd equate that step from a Skilsaw compared to a cabinet saw.
