At Newegg an Antec Tru330 is $46, a Tru430 is $67, and a Tru480 is $76. Pesonally, for such a small price difference I wouldn't scimp on something as important as a PSU. With new video cards already drawing 100w, smaller PSUs don't leave much room for future upgrades. of course, I haven't heard if the current PSUs will be compatible with the upcoming BTX cases/mobos.
