Agreed, the PC 557 is a good biscuit joiner. As to strength of a biscuit
joint, if you are in any danger of breaking a properly biscuited joint, you
got troubles that no joining system is going to solve for you!!!

Now with the PC 557 on the market, who needs to blow that kind of money?
And what does the DOMINO do that the 557 doesn't?
Okay... maybe a somewhat stronger joint, but I don't want to get married
to Festool for consumables.
