Dave;
I used the 1/2 in. version of the product mentioned by Moonman. Also got it from Home Depot. The 1/2 in. version was much easier to handle. There are absolutely no voids in the edges and the top/bottom veneers certainly look cabinet grade. They've been down in my basement for 6 months with no warping issues. I topped the plywood with 1/2 in. Homasote, also from HD.
