Anyone with Experiences with DynapowerPower USA U1 power supplies?

Hey all, I was wondering if anyone had experience with Dynapower 1U power supplies in terms of quality?

Just wondering, thanks

If you are looking at units on mypccase.com, go with Sparkle or Zippy. The FSP branded units may be Sparkle units in disguise but I'm not totally sure about this. I'm not sure about Dynapower. Perhaps OK Wolf knows the OEM.
