I had a cheap pocket hole jig that I bought and never used. I bought the Kreg K3MS and that was that for the cheapy.
I was given a 10" Delta compound miter saw that I did use, but not often enough to warrant the space in my shop. I replaced it with the nifty 5-1/2" Skil circular saw for breaking down lumber and rough cuts, and finish up on the tablesaw.
Most other tools, I buy for a specific purpose, so I don't have this problem in general.
