Today I embarked on the journey of taking a few of my computers new and old and consolidating like files to like folders. Now I need to find the duplicates. There are so many files I dont want to do this by hand (or keyboard?). Does anyone know a free duplicate file finder for os x? preferably Open Source if possible. Thanks!

duff ... I found it to be faster than fdupes, and it's easier to use in scripts. You can get it via Homebrew.

I like FSlint on Linux, with any luck it'll build on OSX. Unfortunately I don't know of any good FOSS duplicate image finder, I have to use Windows ones like XNView.

You can install fdupes from Homebrew. It's a generic duplicate file finder for the command line.
