Steep and Cheap has put the Rab Xenon Jacket back into its rotation for $109.99 plus shipping (about $20 cheaper than the next best price I've seen - which is at Department of Goods when combined with the additional cleansnipe.com discount). The SAC deal ended already (I barely caught it myself) but might pop up again soon...
About the jacket - imagine a garment similar to Patagucci's nano puff hoody, but a full 2 oz lighter. Yep, not only is the Rab hooded, full-zip, with hand-warmer pockets and 60g Primaloft One throughout, it's 12oz for a size large. As far as synthetic insulation jackets are concerned, I don't know of another that has the Rab beat for weight to warmth to feature ratio.
On a related note - is anyone looking for a lovingly used Pata Nano-Puff pullover, blue, men's size large, weighs a little under 11oz? I say that half-jokingly, but there's a very good chance mine will be up for sale on gear-swap once the Rab arrives. I've shaved my body down to a medium these days anyway, and with the hood I can avoid bringing a beanie, saving me another 2oz.
