These Domino threads seem to always go south. I'm going to ask some pretty specific questions so please stay on topic. This is not a loaded question and I have no agenda here. Just looking for information. I don't want this to turn ugly.

I am thinking about selling my Kreg pocket hole jig and PC biscuit joiner to help finance a Domino. I know selling them won't come close to providing the funds to buy it but it would soften the blow a little. My question is:

Would there be any reason why I would regret getting rid of either of these two tools? In other words, is there any functionality that the biscuit joiner or pocket hole jig provides that the Domino would not?

Just to qualify a little bit, my upcoming projects include a lot of built-in cabinetry using both hardwood and sheet goods. Tables and bookshelves also. I also have a lot of shop projects on my plate.

Do not factor cost into this discussion. Let's keep it to functionality only.
