I would check outerwear sites such as Moosejaw.com or backcountry.com. Sierra is not bad but sometimes you may get seconds or irregulars.
I just bought a North Face windbreaker/waterproof jacket from Sunny Sports for $70, but it's not insulated. I would say that there are a lot of choices for all price ranges. I don't suggest Macy's because the quality of their stuff isn't good for their prices.
