OMG. Serious question, at what point does it stop making sense to buy plywood and just go to solid lumber?! Yes, I know ply has advantages, but, man, at 150/sheet; just seems we're approaching the point where it might make sense to bandsaw and joint some wood. Or go really crazy and make your own "plywood" out of 1/4in strips cut out of a nice chunk of solid hardwood from a mill on the bandsaw. Got ol' "3 ply".
