For those in the U.S., here's a possible great deal.  The Thermaltake 1500w titanium PS is $280 at BH Photo Video with a Expected In Stock date of 18 Dec.  They charge your card when it's shipped so no worry about a delay.  I don't think anyone will find a similar PS for this price range, although the Corsair 1500w and EVGA 1600w T2 are rated better in online reviews.  When they were in stock on Amazon, they were around $420.
