a block does not get paid into the pools wallet until 120 confirmations, most pools will not payout before this is reached.

some pools pay earlier, it means the pool operator is taking a risk that the block will go invalid before 120 confirms

http://ozco.in pays out at 100 confirms as a bonus for miners, some other pools do too.

but they charge a fee and only pay 49.5BTC per block after the fee
