I've decided to circumvent needing a planer and off a cut above, with doing a router jig. It's actually easier to get a machined quality surface this way.
I could laminte; but if finish, specific size, and the amount of lamination isn't important, cutting boards are cheap. They're also very different in nature. The stiffness is increased a lot by glue, and the energy won't try to travel horizontal, which increases the wood characteristic instead of acting like a stiff stilt so I imagine. Either way, slab isn't as easy to come by. To have slab cut by the arborist I can buy it from, costs more than than pieces some of you have asked me about!
