There is a post somewhere around here from a few weeks back (I can't seem to find) about some really nice 3/4 ply that HD recently got in that is $24.95 per sheet. I bought some for a project and was impressed (flat, no footballs, minimal voids when cut, etc.) Couple of other folks on the Creek had the same experience. Might see if you local HD has any as it was pretty good stuff for the money.
