Rosewill green series is fine, and the 80+ Gold ones are probably SFGoldenGreen like the NZXT and Sparkle (meaning it is pretty good).
The only thing that OCZ makes that is decent is the "Z" series, and the StealthXStream 400w. Everything else is mediocre.
Same goes for new PCP&C since they are built on the same OCZ platform.
PCP&C (pre-aquisition) are all good, but they lack in effincency, and are often expensive
The HX1000 isn't "crap", there are just better options. It is still a fine unit, and miles better than the Tuniq
XFX is the same as seasonic. Seasonic S12II to be precise.
Everything* that seasonic makes is exceptionally good. *The SS series is ok, but not great.
Enermax is flippin' amazing. Especially their 80+silver units. (Phobus is going to come in here and rant about their slow CS, but it is unlikely that you will ever encounter that.)
once again, you do not need 1000w
you need 750 at the MOST!
you could easily run a 650w unit, but like you said, you want some future expansion
