My current one sucks and emits high pitched noises.
I have found these:
Antec PP412X 400W PSU (a model from their older series of power supplies, not the truepower or solution series) - $35
Sparkle 350W Power G PSU - $22
Nspire 350W PSU - $33 (not sure of quality, but it looks like its good quality)
