Wenzel 2008 Windy Pass 0-Degree mummy sleeping bag
I picked this up because I needed a cold weather bag for a trip I was on last winter. This bag was great, it kept me warm all night. It's pretty roomy inside, good for tall people. The padding is nice and the bag is comfortable to be in. One downside is it's a little bulky, so I wouldn't recommend it for backpacking, but it's perfect for anything else. Very warm bag, and you can't do better for the price ($30 on sale!!):
