Several eBay coticules in the $30-$40 range, a boxed Escher with label and slurry stone for $40 from an antique store, and a blue green unlabelled Escher that came in a lot of eBay hones which also included a coticule, for about $37. I might add that for every great hone I got for low $$ I have gotten a useless stone or lot of junk. You pays your money and you takes your chances!
