Be careful with merged mining. I used to mine at mmpool.bitparking.com and lost a lot of coins because the pool was too small and therefore unlucky most of the time. I hashed with 60 ghash for a week and got a total of 0.17 BTC for that time (while on BTCguild I would've gotten 0.25BTC/day at that time). BTCGuild does offer merged mining with NMC too, btw.
