Hi, Rusty: The diference between left tilt and right tilt, is how you make angle cuts.
With a right tilt, cutting to the right of the blade could trap the cut off, and cause a kick back. On some fence systems with right tilt you can move the fence to the left of the blade to over come that problem. However, you are limited in width when working
with the fence to the left. So if you go with the left tilt you can work on the right of the fence, when making angled cuts. I have a right tilt Unisaw, and I have had it long before they came out with the left tilt option. If you are aware of trapping the cut off
with the blade tilted you can be safer. The important thing is that the table saw is the heart of a wood shop. buy the best saw that you can afford. Woodnut65
