Tone's hitch looks the best by far - barely noticable, and looks as if it was meant to be there. Installation was fairly easy if you have a few basic tools. I can't speak of it's performance as I still haven't towed anything with it yet.
The basic installation uses 4 bolts, but it could also be welded for extra strength.
