The other day I was in HD and found some 3/4" birch plywood that was manufactured by Columbia. It is their their pure bond which is formaldehyde free. It cuts well and stays flat. I looked around just out of curiosity and they had some US made 3/4 MDF also, My question is - has all the complaining on the forum about the foreign stuff finally done some good? The Chinese stuff used to run about $30 - $35 a sheet and the Purebond was $42. I would gladly pay the extra money for the Purebond. And it was actually $2 cheaper than my wholesaler had been charging me.
