Hey Wingnut, The height of the saw will be your choice depending on if you plan to sit or stand, and if sitting, what you will be sitting on. I use the DeWalt stand and I sit on a bar stool. The DeWalt stand allows me to raise the back leg up a couple of inches so the saw table is slanted down. this give better visibility of the workpiece and easy access to all the controls.
As far as height, you will have to experiment to see what is most comfortable to you.
