The $50K Play Action asks for just a $3 entry fee that will more than triple with a score in the top 5%. It's a multi-entry stab (or series of stabs) at solid money with little risk involved, and with less than 14 hours to go, it's less than 50% full.
One of my favorite GPPs, the $70K Slant, is less than half full. A finish within the top 7.5% will more than triple your $9 investment.
The Thursday Millionaire Maker SUPERSatellites aren't filling very quickly. The $1 contest is a little over 50% full, and the $3 game is less than 35% full. I prefer the latter, which will grant Millionaire Maker tickets to the top 13% of its entrants. Get in on these.
