"The obvious" LOL and that is the problem. I think part of the problem is, that the factory shoe is not "stable." They all have the blade tilt/ depth tilt nonsense, and this I think is where the movement comes. One post I saw on the www the guy had a high quality saw with a CAST shoe and even it was out of square.
So far as the comments about a table saw, no, they can be just as bad as a skilsaw, and much more difficult when you have a large panel likea 4x8
