As with everything, quality changes over time(for better or for worse). No guide will ever be true indefinitly. Though I am pretty sure rosewill is not on the avoid List.
There was a time, maybe 2-3 years ago when I couldn't even dream of reccomending a rosewill PSU. But times change, I am not sure of an exact date when they became "Acceptable" to the common computer builder.
They are Cheaper than other brands, but for their price they are "bang for the buck."
I myself would never buy anything outside this list: But thats just because I am anal about power supplies.
