Also dados are prohibited (more or less) in the EU. So yes, there are regulatory issues. And btw, I just cannot find a sawstop to buy here (at a human price)
I'm not sure if they still make it, but Festool and Sawstop are owned by the same parent company, Festool sells the TKS-80 saw in Europe that has the Sawstop tech.
Right, dados are one of the things that baffle a lot of European woodworkers, myself included. Not that they don't seem useful; just a little on the iffy side of safety.
