btcguild also has merged namecoin mining, but I like bitminter better too, because it gets a better hashrate for me 
Bitminter is horrible. I haven't got pass their OpenID requirement and straight out refused to submit my time jumping through another monkey hoop.........what tha hell is wrong with registering a username and password like a normal site?..............this is almost DDos worthy......./rant
plunderisley, go with PPS. Everyone says PPLNS payment will even-out in the long run to make you feel better. I'm on PPLNS coz I let my ASIC rip full throttle.
EDIT: My views has nothing to do with Bitminter's actual pool.
any particular PPS pool?
Like I mentioned I should be a bit over 4GH/s
