cwt is really good stuff, we use them all the time at work, I'd rate them at antec type levels even.

their 550w is great too

It seems all right, and is spec'ed better than an Enermax, which some people hate.

What you have to look out for, is the percent tolerance. In this case, everything is at 5% (which is normal) except the -12V line (10%), but it's not used.

I've opted for this one:
http://www.antec-inc.com/p_true430.html
which has 3% tolerance for the +5, +12 and +3.3V lines.

I picked that one because I'm going for an overclock though, and the extra stability probably wouldn't hurt. I also picked it, because I want the extra power rating, which will make it more reliable over time, and maybe even allow it to run a little bit cooler.

It's still $76 though, and I'm not thrilled at the idea of spending that much money for a PSU, but at least I'm not getting a PCP&C

which has 1% tolerance on the +V line, but costs in excess on $150.

This could also expand into a discussion about the quality of components, and ripple voltages.

For general purposes, an Enermax will do very well.
