I have a biscuit kit for my router table -- $40 -- works fine.

Yup, I use that set-up as well. Splinus Interruptus, I call that method.
I also do it by hand, in a router, with a nice big square base.
Every bit as accurate as the C2 Classic Lamello.

I had the opportunity to use a 557 PC on a jobsite a while back.
Every bit as nice as my Lamello.....almost as nice. Just a smidge more
play in the sliding tracks. Too close to be spending the extra on the
Lamello.
I can vouch for the longevity/durability of the Lamello, I don't know
how the PC will fare under constant shop use.
When my next Lamello walks off the jobsite, I will buy the PC.
