PRIDE: Championship Chaos II (my personal Favorite as this was the first time I witnessed just how dominant Fedor is and this was the first time everyone realized how good he was as he was the underdog in the fight).
Fedor vs Heath Herring, Wandy Silva vs Kanehara in an awesome match, Randleman vs Yamamoto, Arona vs Ninja.
PRIDE:Body Blow (pride 25) one of the best ever in many fans opinions including myself. Epic Fedor vs Big Nog fight, Little Nog vs Nakamura, Anderson Silva vs Newton, Hendo vs Oyama, Saku vs Shembri and Rampage vs Randleman. so many great fights on this DVD.
Those are my personal fav's.
Also, Best Buy carries them as well.
