I lost mine and all I did to replace it was cut a small branch, sharpen the end, and stick it in the ground--it worked beautifully! Got a NICE tom at about 7 paces (from where I was sitting--the decoy was set up to my right several yards from me).

I was using a Feather Flex type decoy though--I' m not sure if this would work for your decoy though. You might consider it though and save yourself some bucks for a replacement stake...
