is another one, not free but in my own opinion it's better
than RoadKill. (I'm not saying RoadKill is bad).
My only issue with Headus, and the reason I stopped using it was because if I spent a month or more away from it, I'd completely forget the hotkeys, and it's very
hot-key dependant. Which is both a blessing and a curse.
Also, it's worth noting... that Max's (if you're using it?) default unwrapping tools are more than enough to get the job done. I mostly use just 4 parts of it. Planar Mapping, Relax, Break and Stitch (you'll want to hot-key stitch). Seriously... there is very little you can't do with those.
