Their FSP Aurum, Aurum CM, Aurum Xilenser and Aurum Pro series are all known to be good models and are often used by other brands.
The downsides of the Aurum and Aurum CM series, in particular, are noisy fans (they spin too fast, unfortunately I think this was probably necessary to keep them cool enough) and ripple and noise suppression definitely reflect their budget nature. This might be okay if competitors didn't beat them in both those aspects.
