I found this bag at Sierra Trading and have to say that I am very happy with it.

Warm, quality construction and great for car camping since at 3 1/2 lbs a little heavy for backpacking. And a steal at $50 if you can get it on sale. My feet were a little cold but I think that is because it has a large foot space, toss a jacket down there and it is fine. In a tent it will probably work to the 15 F it is rated at. I had a tent collapse during a snow storm in October (don't ask) and despite a soaked bag I was warm all night.
