My wife has the Stoic down jacket, which we picked up last spring at a great price. They are currently selling it for $110, which is more than we paid, but still not bad for what you get. On my scale, her size small weighs 10.9oz and has a very flattering cut; 750-fill.
One jacket from them that just came out that I would be watching for sales on are their Stoic down anoraks... pullover style with a kangaroo pocket, hood, buttons instead of a half-zip, and 850-fill down. List price is $179, but in my experience, everything Stoic comes down at least 30% pretty quickly as backcountry.com has pretty quick turnover for their house brands. They don't list a weight on the women's jacket, but the men's is listed as 8oz... might be a great piece of kit.
In my opinion, though, your best deals are going to be signing up for emails from Sierra Trading Post -- they send special deals every few days to your account, and you can pretty frequently get 30-35% off, plus free shipping, in addition to their existing prices. It looks like they've got a couple of jackets that would fit your specs.
Mountain Hardwear Nitrous Down Hooded Jacket is $155, so would be ~$100 with a coupon.
The Mountain Hardwear Phantom Down Jacket doesn't have a hood, but I think has more insulation and would be a similar price.
If you want something even warmer, the Lowe Alpine Iceshield Down Jacket - 750 Fill Power would work out to ~$120.
Those are just quick search results. If you dig deeper you'll find even more options. Basically, in the $100-$120 range, you'll have choices at all weights and warmths. I'd grab something soon, though, since I would expect the (low cost) options to decrease as people buy out the rest of last year's stock and prep for winter.
