Leecraft Zero Clearance insert or homemade?

I was thinking of getting a Leecraft insert for my PM2000 but before I do, I wanted to check in here and make sure I'm not "being had by marketing". Those inserts seem nice, but is it foolish to buy this when I can easily just make one myself? I do like that the leecraft has the height screws, and I suppose I could just add those to any insert I made myself. I'm also thinking, I would need one for a dado, one for regular cuts, and then one for angled cuts, so maybe it's more intelligent to make my own...

Thoughts?
