I recommend to watch the videos for the rabbit rig before you head on doing your own tutorials.
Thanks Pancho. I have watched the rabbit rig tut, and I didnt like it. The fact that you have to manually keep track of relationships thru ID's on custom properties is suicidal. I'll admit, I stopped watching it when he started running the scripts to set the ID's. That approach just seemed so brittle to me.
Since ICE is modular, there are various methods of achieving the same functionality. I believe that's why the ICE Kinematics docs says..
There is no universal recipe for making a rig. Each rig is a response to specific production needs. ICE provides great flexibility in this regard.

As to the free tutorials, I'm more than happy to refund your time spent viewing them.
