So my Diablotek power supply was designed in hell? (no replies)

I thought mine was a bit loud, but after some general research am finding that's the least of my worries.

A few years ago my next door neighbor needed a power supply, and bought a Diablotek for $50 locally. I looked it up on eBay and it was $15 at the time, shipped. I was installing it when she told me she was moving and I could keep the power supply. Then another neighbor asked if I could fix his laptop. One evening's work later, they asked if I could use a computer that lacked a power supply. Sure. Crazy how that fell into place.

Now I realize it's too loud and I should think about replacing it, and Tom's Hardware and other places insinuate I've been lucky it didn't fry my system several times over. True, Debian ran hot and I've had to replace RAM several times, and the power supply might have something to do with it.

So if you don't mind, I was wondering if there's any low noise units in the 600W range that are at that sweet spot of low cost and reliable performance? I'm seeing some names at eBay for $20-25 that aren't on the Ton's Hardware no-buy list, have one large fan and are said to be quiet, but you guys are smarter than the average bears...
