Just recently ran across a great building board... It seems that they were tearing down an old bowling alley... guess who was in the right place at the right time to get their hands on a piece of one of the alleys! Flat, smooth, won't warp, and maple! Just put it on some base cabinets, threw some celotex (ceiling tile stuff) on top for pins, and off we go! If you get lucky, you can get them in any length you can haul away. If they're not trying to salvage them, just bring your chainsaw!
