Don't know the buyin, but this may be a good tournament http://macaudailytimes.com.mo/baccarat-championship-breaks-world-record.html
There were different buy-ins in eliminations rounds all over US and the world. Top 3 players from a few locations of multilevel eliminations were put into "semifinals" and about 100 ppl were invited to play in the first round. This was for super high-rollers, let's just say that one trip loss of $100K would not be enough to qualify. It is astonishing how many people gamble at huge levels. S. Yama
