Shell manufacturers

Hi,



I'm planning a DIY build and am already off to a bumpy start. I've decided to go with walnut shells but cannot find ANYONE who supplies them. Keller is not currently manufacturing any, can't find any of their suppliers who have any, I think Allan Tocknell of Tee drums produces or has walnut shells, but is not replying and i've heard terrible things about his customer service.



Does anyone know of anyone, anywhere on this planet, besides keller, who manufactures walnut shells?



Thanks
