If you have Antminer S3's; I think your best luck would be with finding your nearest P2Pool node and mining there.  I'm currently mining P2pool on Coincadence.  The operator is active on these boards if there are any issues.  The thing to remember about P2pool is that it takes a long time to start getting payouts to discourage pool hopping.

Otherwise, BTCguild seems good. 

I have my R-Boxes on f2pool for now to see how it does.
