Zalman or Silverstone?

[Dorkenstein]

Would a Zalman 750w PSU or a Silverstone PSU of the same power be the better buy? I was looking at the Silverstone but it might not fit in my case because it's really long. Thanks for any help.

From a personal preference standpoint, I'd take the SilverStone. The 850W and 1000W Zalman are made by Enhance and I like them, but the 750W and below are FSP. Although they've made improvements to their group regulated design since the Epsilon first launched, I kept help but feel let down by FSP.

Question: Why only those two choices? There's gazillions of PSU's out there. What criteria did you use to narrow to these two?
