I found some "3/4" MDO at Builders Discount center for $25 a 4 x 8 sheet. It is 7 ply not counting the MDO layer (MDO = medium density overlay, which is a thin layer of mdf over the hardwood core). The hardwood face on the other side is smooth and close to walnut in color, altho it has more of a reddish tint (about as thick as the oak veneer on the borg stuff). Very view voids, and those were in the 1/4" diameter range. Works great for cabinets, especially of you are going to paint one side.
