I've used various older Antecs (235-250W) and a couple 330W Enermax PSUs, and have been satisfied.
Based upon what I've read, if I were looking for a new PSU I'd consider the recently introduced Antec TruePower series (330W and up) and also the HEC/Heriochi PSUs. NewEgg carries both brands -- you'll have to look under "Compucase" to find the HEC PSUs.
Leadman/PowMax are also supposed to be good, although they don't seem to be as common.
Also, keep in mind that although PCP&C is a good company with good support, they don't really manufacture anything. They sell rebranded 3rd party products, and provide their own support. If you're willing to pay a premium price for above average support, it may be worth it. But I question how often (if ever) one would actually need support for a PSU...
