Bamboo and other wood

I've been looking at wood lately. There is a store in Seattle called Environmental Home Center Environmental Home Center that has environmentally-friendly building materials (as you might guess from the name) but they are EXPENSIVE. How is a piece of plywood (kirei) made out of reclaimed sorghum stalks cost $199.00 for 3/4"? They also have some beautiful European hardwood plywood that starts at $116.49. Ouch. Can't go that route. They also have beautiful hand-made recycled glass tiles but it's $28.49 - $62.89 per sq. ft.

There is a spot called Phoenix Organics in Phoenix, OR Phoenix Organicsthat sells bamboo plywood but it's feckin' $261.63 for natural edge grain solid 3/4" x 48" x 96".

After several more hours of searching (thank you, corporate job) I found some FSC-certified lumber stores right here in Seattle. Don't understand why it took so long to find them; I think I traced them from the FSC site. One is Dunn Lumber which has 11 stores in the area. They have FSC (min 70%) CDX 5-Ply 1/2 sheets for $22.33 each, and FSC Hemlock 2x4-8 studs for $4.44 each -- much better.
