Jonnyguru.com is fantastic, no doubt or issues there at all.
Ripple wise it really depends on what flavor of ripple you're looking at. The main waveform should definitely be within spec, and under half spec (so 60mv for 12v) is certainly preferable.
Transients are another story, one that for one reason or another very very few PSU review outfits test for.
That may be because it takes truly staggering transients to cause issues, that may be because they like to have a standardized 1ms/divider scope setting (the longest transients I've seen last a whopping 100 nanoseconds), or it may be because the sites don't view them as an issue. I don't know.
Personally I do test for them as the ATX PSU spec calls for testing for them, though I generally disclaimer the results explaining the transients aren't as important as the main waveform.
In any case, if JG/OW recommends it, it's good!
If I can't find at least one in depth review of a unit (needs to have disassembly, scope testing (no $50 USB scopes, please) and a real load of some sort. It doesn't have to be a multi kilobuck digital load (mine isn't), but it does need to be a real, halfway decently calibrated, load. No computer hardware based "test systems" that might draw 360w on a bad day!
The OCZ ZT PSU I looked at was good, the ZS unit reviews I've read have looked pretty good too. OCZ bought PC Power and Cooling a couple years ago and have been working them into things I think.
