The only big one that's missing from that list is Bodog. Grab as big a chunk of change as you can and put it in the site all at once, and magically your account is credited with 110% of what you deposited. Sweetness. The bonus clears at a decent rate, too. But do note that you're going to be playing there for a long time, because if you want the bonus, you can't cash out until after you clear it.
