Green Treated is a fine value and gets a bad rap sometimes. The problems people have with it are often due to improper building prodecures. From time to time I have to replace a rail spindle or correct a separating corner, but for the most part I find green treated very acceptable, provided that apply a sealer to it after it dries.

There is a new kind of treated lumber available, arsenic-free: It's called AC2 and replaces previous types of treated lumber that are now being taken off the market.

I prefer working with cedar because of the lack of chemicals in handling, the lightness of the wood and the nice smell. But I am really only interested in giving you want you want for your dollar, and green treated is a great way to get more square feet per buck.
