Too bad you weren't using this pool: http://bitsolo.net/  They promise to pay the full 25 BTC to anyone who finds a block. 

I just got an Antminer S1 to replace my USB block erupter.  The Antminer is hashing away in a large pool.  I am using the block erupter now in the pool above.  I know it's a one in a million chance.  But maybe I'll get lucky and find a block.  It' like playing the lottery.
