Agreed, I've also built sleds using the 5 cut method based on William Ings video (which I think Katz-Moses refers to). I think the jig might save about 1/2 hour of your time. So at $198, you would have to make a lot of sleds to justify the cost. Maybe worth it for a commercial shop making dozens of sleds in a year, can't see it either for a hobby shop.
