Oh yes, that was a score but you don't have to use Bamboo boards. You can get other woods or find bargains at restaurant supply store or even a lumbard yard...
I got these at T.j. Maxx in NYC. This chain of discount clothing and household items operates under different name in different places; Marshalls, HomeGoods and A.J Wright in the US. Winners, HomeSense and StyleSense in Canada and T.k Maxx or HomeSense in Europe. I always find good cutting boards there. Occasionally I load up on KitchenAid accessories and cookware from All Clad and Le Creuset there too!
The rest of the accessories I got at Home Depot. The only exception is the Microwave Beacon Tray (turned draining board...) which I got at Bed Bath & Beyond.
