Manfrotto 155 with camera platform
The Manfrotto 155 system is not exactly a tripod head, but it's not not a head, if that makes sense: The system includes a double ball joint head with threaded studs to give you multiple mounting options and a detachable camera platform with a few mounting option of its own. You can use them together or apart. If you think you might need to mount a camera to something in a slightly less-than-usual way, this is a pretty nice setup to have at hand.
