My father had an old Craftsman cast iron table saw that he made a stand for. It was made out of 2x4s and plywood. He used two lawn mower wheels to make it movable. It was a wheelbarrow set up. The wheels would only touch the ground when you lifted up on the two handles on the opposite side. The motor was on the same side as the wheels and the handles would fold down when not needed. I doubt even today it would cost much more than $30 to build.
I think really that's the ticket here.
