"Is any one surprised by how good their system turned out."

Not me...........  Its ok, getting better. Untill the system is a push the button, go and not worry about it till tommorow system, Ill be more than pleased.

Im sure there are guys out there who are totally amazed at how accurate and easy these things are.  Im just not one of them.  Going markerless would not be a good thing for me.

Good luck
