downloading test builds

[Riptyde]

Ok....it could be right in front of me, but where do you download the latest test build for 2.5? Is there site someplace with a bunch of them? Are there test builds from the blender people.

I ask because I've seen tutorials that reference a specific build but I don't know where to go and get it, and if there are updated builds I'd like to stay on top of them.

Thanks for the help

Rip.
