You can buy regular Schizos from Marker and put them on any ski you wish.
Or you can buy a Kung Fujas, Extreme, obSETHed, and HellBent with Schizo and built in inserts.
You can also buy those skis flat and put you own bindings on them. Then they come with NO inserts.
The Schizo system is pretty crazy though man. Once you set it up for your boot size, you don't even have to unclick from them to change position. You just use the little key to crank them forward or backwards.
Sean Decker skied on them at Hood all summer with no complaints, so they seem to have built them right. I have only skied a few days on them, but that wasn't putting them through a ringer, so I was stoked that Decker couldn't fuck them up.
