I have seen the last few PPV fights that I cared about for free. There is two options. You can go to any Buffalo Wild Wings and watch it, done it 2 or 3 times but you have to buy a beer and put up with drunk people. The other option if you have a computer with a decent internet connection. PM me and I will try to find the program for you. It is pretty sweet but it is only a live broadcast so you have to have it up during the fight if you want to rewind. It is kind of like a DVR for your computer.
As far as Machida goes, the fights that I have seen he blocks or moves out of the way from everything and when the other guy steps in he knocks them out. I heard his last showing was boring though.
