Source needed for KCN, potassium cyanide

[Bob Salomon]

For fixing wet collodion plates, I prefer the color given by KCN. Does anybody have a source for this where it doesn't cost a fortune or require a dump truck to deliver?

Yes, I know it is toxic. I know other things work. Prefer KCN.

Thank you all.
