Unless you're an absolute freak about having no noise whatsoever, it's really hard to justify spending over $150 for a 350W PSU. I mean, Antec isn't really what I'd call crappy, but that Phantom is awfully pricey. If you're gonna spend that much cash on a power supply, save another $50 or so and get a PC Power & Cooling 510...but those tend to be a little on the loud side. I think ProcalX mentioned Seasonic power supplies also being pretty quite.
