Trinus is the only one I've heard of, so I'd start with that one. Both have free trials, so you might as well try both. I don't think either one actually handles the 6DoF headset or controller stuff natively though, so you'll need PSMoveService too.

For PSMoveService, you don't necessarily need a PS3 camera anymore, just something that works with OpenCV. $8 for guaranteed compatibility sounds like it'd be worth it though.
