I would give my right arm for the chance to buy two or three 8' X 4' sheets of baltic birch phenolic-coated plywood. If I order it from northern state suppliers(e.g. New York), the motor freight would be extremely expensive. Anything closer to home?
I got mine at Coble trench located at Lee Ave & I85 in Greensboro. It is right off the service road on the north side of I85. It was $125/sheet and they let me pick out the piece I wanted.
