When you find your hydraulic lift cart, be sure to share it with us so we can drool. That sounds like a great idea to save the back. I have to cut plywood down to be able to handle it so most of it gets cut with a circular saw and only smaller pieces on the table saw which could never cut full sheet anyway.
