Bellagio has a $500 tourney every day, with a 1K buy-in on Friday's. Pretty decent structure as well. I finished 5th in this one when I played it in September, was at Sam Grizzle's table for some time.
The Wynn also has a $300 I believe. I was first one out of that one the same day I final tabled Bellagio.
Those are the 2 I have played in.
