Looking for 3rd party TFTP server app

I am wondering if anyone can recomend a 3rd party TFTP server app?

Before we go there, I do mean 3rd party not a front end for the built in mac tftp server product. Which I have had countless problems with, yes I set the permission, yes I moved the tftp root to a public locaiton where the whole world has rights, yes I have used the fabrizio's app, yes the permission light is green for folder and path permissons, yes I have edited the path in the tftp.plist file. No slight to fabrizio I am sure he is a great human being, but my tftp server status never enters a running state both with his front end app and using command line sudo launchctl load commands.

Long time network admin, newer mac user, needing a tftp server to upload/download configs for cisco switches and routers.

Any help you can provide is greatly appreciated.
