Get the Fortron FSP 530. It's $75 or so at Newegg. It's a great PSU, and a lot of people use it. And yes, it is worth it to spend more on a quality PSU. I saw 2 systems in the same week come into my local computer store with PSUs that burned and took out everything in the comps. Ever since then, I've only wanted to use quality brand PSUs.
