I'd say go for the Epx 9NPA+Ultra, too. They're great boards. I used one when I built a computer for a relative last year. It's overclocked to a nice speed, and it folds almost 24/7.
I, myself, have an Epox 9NDA3J (nForce3). I bought it from somebody here on AT back in January. It's been a great board...overclocks well and is very stable.
