I'm a huge fan of the 36+3 6-Man Turbo SNGs on Stars. Payouts are 140.40 for first and 75.60 for 2nd, and they only take about 30-35 minutes. The fact that there are only 6 players still allows for a decent amount of play (unlike full table turbos where there are still 9 players at the 100/200 level) without taking a long time, which is great for me, because I rarely have 1.5 hours to dedicate to a SNG. There are also a wealth of bad players to prey on.
Also everyone's favorite, the 22$ 180 Man SNGs on Stars, whenever I have time for them.
