1. A $12 buy-in can win $9,000
2. The structure offers plenty of playing opportunity;
3. Each tournament only consists of 20 people.
4. If you play well, you could theoretically play forever on one buy-in.
5. You can play at your own pace and according to your own schedule.
I haven't played any of these yet, but plan to soon.
